Quickly buy your starting items and run to protect your jungler and help them leash. Do not pick your spell yet. If your team wants to invade pick E to start with instead of Q. If you get invaded same thing. Otherwise start normally with Q.

Request the second blue from your jungler mention to them it spawns shortly after 7 mins and so does the opposing teams. Most people don't realize this information and it helps organize some counter jungling if your team is interested.

Now Middle lane is very often a misunderstood place to play. Some people only last hit minions or stay middle the entire game and do not gank. I will inform you that both of these are incorrect ways of playing middle. Minion control is very important.

While middle your goal is to slaughter all the minions while doing as much damage as possible to the opposing middle. If you are able to kill all their minions and have a lot yourself. You can very often take the other middle down to half health if they are not careful from minion damage alone.

But doing this leaves you pushed forward for a jungle gank. How to avoid this is simple. Non stop be moving don't stand still to avoid any skill shots. Also Keep to the middle of the lane and away from the bushes as much as possible.

How to Harass and stay safe: Use your Q spell preserve mana don't use other spells unless you know it can get you a kill or you have blue buff or you have tear. You want to line your Q up so it deals damage to minions and possibly hits the enemy champion. Also every time you cast it run backwards soon as it casts out. This helps defend against jungle ganks and snipe spells.

Okay now soon as you hit level 6 and get your ult you need to start looking where you can gank. Look for lanes that are pushed forward or if you have poked the enemy mid to death you can jump tower with your ult to finish them off. Don't worrie if you die as long as you get a kill. Ahri has expensive items that scale better then other builds also she has true damage so her getting a kill does a lot.

Now ganking a lane I usually prefer to gank top by this point if possible because top rarely has an active ward at this point. Where as bottom usually does. If you gank bottom they have to be pushed really forward and you have to get there while things are a bit intense. Which if you ult in you can get a kill or at least do some serious damamge for your team.

In the case you end up in a 1v1 hit them with your Q and run back. If they follow pop you're W and hit them with E while running. Pop your crystaline healing/mana all 3 times. Stop running and hit him with your Q while he is charmed. Soon as the charm is almost done start running away again. Rince and repeat. You get them to follow you if they get to close and you have a panic situation you pop your ult and jet out of there. If they get low on health you pop your ult and kill them.

During a team fight you do the same thing. You take front point as if you were a tank. You run up throw your Q at them and run back. Run forward keep doing it. Get them to follow you and burst your spells on them. Once a team fight is stationary just stand back and pop your spells. You staying alive however is more important then you doing any damage so if they chase you down and get you low on health let them chase you and ult away. This pulls 1 or more champions away from the fight so your 4 team mates have an easier time killing them and you don't die and feed the enemy anything. In the case you are left alone and your team is winning. Save your ult till they start running pop it to run in and finish the enemies off.

it is very important that with all your AoE you farm a lot keep your towers safe by killing any building up minions on any of the lanes. Always be pushing towers but be smart about it. Don't push to far forward when you could easily get ganked. If you are pushing a tower always stay as far away from where the enemy could come from as possible this way you have time to ult away if worst comes to worse. It also can set you up for being able to kite the enemy and get a kill or lower them enough that by the time your team gets there they get an easy kill or an easy team fight. Also don't forget your Mana shield!!!

I'm MrEnder in game if you need a mid for your 5v5 ranked team. I'd love to get out of solo ques :) thanks for reading and hope I helped.
