Threats & Synergies
Avoid poke, you beat her past early game if even. Juke her E Q.
He can dodge Q, so save it. If u dodge his q u can force a short trade or zone. When his q is down, u can use E to force him to use E, then you can zone or he will take your Q when he goes for cs.
You beat her early and mid as long as u hit skill shots. If you miss Q, she can jump on you and outtrade you hard.
Wait for her Q to be on cd before u q. They always tumble forward when 6.
Use minion wave.
Do not do extended trades. Warn your team if he is missing as he is the best at applying map pressure. You and nami can all in twitch at lvl 1 with ignite if his janna uses shield on herself or some support misses her skill, even if she exhausts you.
Do not do extended trades. Usually after first recall, if your W is down, do not auto him and keep ur distance. Usually after first recall, if u predict he will use W to dodge forward ur Q, then Q in front of him auto then W bak and ult.
Even in lane but your poke is better for team standoffs.
She outrange at lvl 1, call a gank if she is aggressive. You can W through her E if used right when she deploys them.
supp: Avoid her stun unless you and your supp are ready to fight.
Support Brand: His Q does absurd dmg with ignite. You must dodge well.
He can cancel your W so wait for cc to end before using W, but of course try to avoid the cc in the first place.
He can cancel your mobility with his cc. He is high skill cap though. When he starts Q animation, flash it
Your W is one of the two longest escapes for an adc, which easily avoids morgana ult. Your magic dmg can burst down her black shield to allow your teammate's cc to lock down the enemy.
She usually starts Q so just dodge it easily by pretending to be aggressive or juking cs. When she uses E on ur support or u, be prepared to juke her Q. You can lower her passive dmg by being behind a minion.
Her movement spd makes it even more easier to dodge ur Q. Bait her shield and switch targets. Focus janna when jungler ganks for u if u can. When doing a trade, if she has plenty of mana, predict her q. Get a gank if she plays up.
dont be next to minions that he can W to, either fully zone or dont zone, his W is 14s while ur W is 26, during all in save q until his wall is down, suggest pickin a different adc
do not auto trade when her ult is up as it is harder to dodge
stay away from wall, her speed and dash is more threatening than a vayne E and ali W, flash out of her yellow field then W if caught badly
stay away from minions, allies, and walls, only trade when his q is down
jung: never 1v1 him and wait for help, have pink ward until 6 item build and put in bush during fights or if no bush put where you are, wait for him to show in minimap at lvl 6 or when enemy laners burn cc and miss u can trade for a bit then back up, generally stay grouped and let tank farm side lane with teleport
supp: juke her skills by moving into range of her skills then back up, get gank, if your are getting hit by her plant back all the way up to drop aggro
juke her e by walkin to her then backing up from her max range, dont use W to trade cd with her E since her E is 8s cd poke her often when her E is down but care flash Q
team fight: hit him with long range skills, when his Q is down then u can auto him, his Q is 3s cd, if enemy team has no mr and will not build mr get morellonomicon
jung: even when ur fed dont let xin auto u, if he dash on u W away immediately before he gets his auto and dont worry about his ult since u r marked by xin and wont cancel ur escape
team fight: do not auto him unless he has 2 stacks or less or cc'd...even when ur fed
do not be near minions when his grenade is up, avoid his 4th bullet by giving up farm, his W goes thru minions, avoid near dead allies for they can explode, he beats u lvl 1-2, get gank against his immobility
when jungler is mia and he has flash, dont be in his W range
be more careful when he has ult
team fight: burst her down, dont flash or w when she ults as you will still get hit by her, assign a teammate to hard cc her and tell team to wait for exhaust cd
use E to bait her spell shield possibly, do not use Q unless her spell shield is down
when he uses W, ping team to back, flash his stun if its going to hit, get hexdrinker even if he builds tanky
can 1v1 him end game w/ mercurial and he has no void, stay out of his ult at all costs, dont flash when his Q is up
can W his W right before he appears next to u, when ur W is down dont auto him unless he uses W on some1 else

Then usually a Sorcerer's Shoes since much of your dmg is magic, first used by the player Score from KT Bullets. The item after Trinity Force and Sorcerer's Shoes is usually Rapid Firecannon, then vary with situation.
Rapid Firecannon should be bought after Trinity Force Sorcerer's Shoes for a quick item spike.
After Rapid Firecannon, get Infinity Edge if you can auto often in team fights or Essence Reaver if you cannot.
Get The Bloodthirster if you are running a poke comp as the sustain and shield makes prolonged sieges better for you as you wear down the enemy and you are full hp. The shield also helps tank 1 or 2 tower shots. Also if only 1 or 0 enemies are building tank.
You get Blade of the Ruined King when you are against 2 enemies that are building tank. Blade of the Ruined King also synergizes with Gatling Gun.
If you are not in danger and not part of poke comp then you get Infinity Edge after Essence Reaver, unless you bought Rapid Firecannon.Testing
Don't get Last Whisper. With the changes to corki's damage output, Void Staff is better than Last Whisper in all cases and should be bought when they build Negatron Cloak or Aegis of the Legion. Corki can still do plenty of damage without penetration items so go with survival items like The Bloodthirster and/or Maw of Malmortius.
As for defense items, Quicksilver Sash is great against Zed, Thresh hook, and other critical cc. Banshee's Veil is pretty good against Lee Sin, Blitzcrank, and other strong spells. Guardian Angel if you do not need the previous 2 defense items. Randuin's Omen if against full ad team. Read mid game chapter for trinkets. Maw of Malmortius, with the nerf to Mercurial Scimitar magic resist, can be added after Trinity Force if you are against a team with lots of magic and weak dmg tank or no tank, for example Syndra, Rumble, Rammus or tank Jarvan IV, any adc and any support.
Get Elixir of Sorcery when you expect a big fight; it is better than Elixir of Wrath since its passive is wasted as you do low physical dmg. When lvl 9 in game, get Farsight Alteration to ward your jungle bushes.
lastshadow9 had said Corki should sell Sorcerer's Shoes end game for Luden's Echo. It sounds good, I'll try it out when I have that much money.
Use Missile Barrage to activate Trinity Force procs when killing structures, but in fights you generally use any one skill before each auto. Also in fights just use Gatling Gun right away since your Missile Barrage has good cd to activate Trinity Force procs.
The Package from Hextech Munitions does an insane amount of damage but you don't always get to use it. Usually used to knock aside enemies and make sure you can get out alive, if you can't get out alive then don't use it offensively. Remember you get an extra Valkyrie after using the Package.
Thresh needs kill pressure, which Corki applies.
Poke comps with many ad sources of dmg can use Corki rather than Lucian or Caitlyn.
Team with heavy ad dmg benefits with Corki.
This champion is not good with double ap.
Leona needs kill pressure, which Corki applies.
Nami and her Tidecaller's Blessing on you with sorcerer's shoes can do a good amount of dmg.
Jayce physical poke dmg coupled with your magic poke dmg can siege very well. You should have an ap top or jungler. For example Maokai or Rammus.
Janna and her disengage kit lets your team poke more. Her ad bonus of Eye Of The Storm lets your skills hit harder.
If you killed your enemy laners and you do not know where everyone is on the map then you should go to your tower and recall. Do not risk getting killed by their jungler or whoever. If you got a successful jungler to gank you then ask him to push with you unless you are all low enough for a triple kill. After recalling, buy while walking to edge of fountain always until 20 minute mark.
It takes 9 minion kills for duo lanes to level. You should count the minion deaths on both sides to see if you get lvl 2 first to go aggressive, both sides get lvl 2 at the same time, or if the enemy get lvl 2 first so you back off to tower. If you get lvl 2 first with support and you all in then get Gatling Gun. If both sides get lvl 2 or they get lvl 2 then u judge which skill to take at lvl 2. Once lvl 3, if you dont expect an all in or gank then take a 2nd rank into Phosphorus Bomb for better trades/poke.
You should conserve mana by not using Gatling Gun unless there is an all in or gank, or only use it when Thunderlord's Decree is up then back up once it procs. When trading, use Phosphorus Bomb followed by 1 auto then back up. You use Phosphorus Bomb first since if you auto first they can dodge Phosphorus Bomb easier. If you are not full hp and just want to harass then just Phosphorus Bomb since it is a bit longer range than 550 range auto. Missile Barrage, like other skills and autos, should generally be used right when they go for a last hit. If you hit them then its good, if they dodge it when his cs is about to die then he will miss the cs. A win win situation. If they are about to harass you when you go for cs, then u need to pretend to go for a cs then back off to the left, right, or back to dodge the skillshot, such as Aqua Prison.
Ward mainly when you push to enemy tower or for lane bushes. You can fake ward by walking to a spot and pretending to ward. If the mid or jungler(who is missing the most) is missing then u should expect a gank and should back off. Watch for top lane Teleport as well as you cant all in unless your jungler and top lane is ready to help. Get all 3 skills lvl 3 if you expect gank or all in. Play back, preferably at tower, if your support roams. Generally when your jungler comes, u let him show first before engaging since u don't want to die in a 2v2 before ur jungler gets to do anything. You can harass at enemy tower at the top edge toward river of lane just outside tower range only when they go for melee minions, and only if you know where everyone is and Teleport cooldown.
At the 8 minute mark your passive spawns The Package. After you base and buy use Valkyrie or walk while buying to get to the Package and pick it up. Make sure you pick it up after you finish buying since The Package does not last forever.
Get all tier 1 towers, trading towers is fine.
Call for help to ward enemy jungle if your team is ahead. Try to have a pink ward to contest objectives, sell doran if needed. Buy Elixir of Sorcery if you expect a fight. Get Farsight Alteration at lvl 9. You should generally be grouped with your team. Read items chapter for more info on trinkets.
Don't let your teammates push past river without grouping to ward enemy jungle. If your team is even then generally ward rivers and wait for next dragon fight. If your team is behind then generally ward your jungle/river and hope to get a pick. Try to get enemy buff timers then set up a minute before with deep wards and a pink when your team is ahead.
Your team can make plays when your massive minion wave is pushing by making a play on the opposite side of the map with an objective or decent minion wave to push. Or use the big wave by going with the huge minion wave for a strong siege or tower dive in that lane. DO NOT DIE FOR A TOWER. Even if it is one hit away, just get it later when it is safe.
Try to slow push a side lane by telling your a teammate to leave 1 siege minion and 2 caster minion alive, so you can coordinate a timed push on the other side of the map w/ the massive wave. If there is backdoor pressure on your base, it is more imperative to use Farsight Alteration in your jungle bushes and lane bushes.
If they have Fiddlesticks, Nunu & Willump, Master Yi, Udyr, Shaco, Elise, Karthus, Lee Sin, and possibly more(not to mention laners helping out), then you need to keep it warded from a specific lvl onward for a possible sneak.
If the enemy starts dragon, poke them until dragon is half hp, then fight. Poking them makes them disoriented to either finish, run, or fight. Dragon does aoe so if you start it, have one person in the pit to tank it away from team.
Do not do elder dragon with 2 people or less.
As purple team you want to pink outside the pit and sweep inside the pit.
As blue team u want to pink in the pit near the entrance so that the enemy doesn't kill it over the wall.
Do not stand behind baron when taking it. It does damage to everyone behind it.
Your teammates need to have sweepers and pinks to help. As for positioning when taking baron you need to stand outside the pit with your carries. As for ward kills in the pit, support should be the one since support's dmg against baron is least important. When the enemy is in the baron pit, hit the baron to make it hit your enemies. Never use your cc at baron when enemies are around. One person should zone the enemy team if they are coming to stop the baron attempt. Communicate with your team beforehand to finish, run, or turn to fight.
At 20min and onward you must ward it against sneaks from high objective junglers such as Nunu & Willump, Udyr, Karthus, Fiddlesticks, Master Yi, and possibly more(not to mention laners helping out).
Corki should have not gone after caitlyn and just use his aoe damage in that jungle fight on the other 4 members. He wouldn't have gotten hit by any cc.
Another example: if Leona and Lucian are in your range, then hit Lucian while avoiding Leona skill set as best you can. If you are in danger then generally you want to go to your teammates rather than away, unless you got Fizz ulted or something.
The Package from Hextech Munitions during a team fight depends on your situation. If all enemies used all of their cc then you can Valkyrie in, then Valkyrie out in a 5v5. Primarily use it to knock aside multiple people rather than hoping they will walk on the trail. In early game small skirmishes like 3v3 or 2v2, you may not need to Valkyrie out right away since enemies usually won't have the burst that early and are getting hit by your teammates.
