PROS:

- Benefits attack-speed champions greatly, like Diana Tryndamere etc, on top of your ADCs.
- Hard to deal with poke in laning phase.
- Punishes immobile champions very well.
- Mixes up the draft.

CONS:
- Very squishy
- Limited build options
- Hard to play optimally.
- Very few good lane partners.

There's 2 main mythics to buy, and it really depends on how fast you're dying when you decide to Cataclysm an enemy. If you're doing really well, you can either rush Moonstone Renewer or Zhonya's Hourglass. If you're starting to fall behind, then Locket of the Iron Solari is your back-up option. Cloth Armor and Ruby Crystal and Amplifying Tome are recipes for a lot of times you're looking to build, and you'll likely start with those on your first recall.

Mythics

Reasons to get Locket of the Iron Solari
- You're either even or behind.
- There's a lot of burst on the enemy team.
- Safe choice overall.
- Your team has no one else to engage except you.

Reasons to get Moonstone Renewer
- You're ahead and you're looking to keep having your poke be very potent
- Snowballing.
- There's someone else to engage for you.

Legendarys

Zhonya's Hourglass
- Allows you to e-q-r then q out.
- Much better when the armor benefits you more from mostly enemy AD team comp.
- You're getting ahead botlane and the AP will actually still be useful early.
- Possible to rush this as first item if you're ahead.

Knight's Vow
- You have a fed carry that you can keep alive for a bit longer.
- Cheap Legendary for mythic passive and lots of desirable stats.

Thornmail
- If the enemy has a lot of healing, on top of a mostly AD composition, then building this would be pretty efficient. Champions such as Olaf Aatrox Darius and Goredrinker users.

Redemption
- Plenty of desirable stats here, and very cheap.
- Might actually be not too bad to even rush as a first item.

Vigilant Wardstone
- Cheap Legendary item for mythic passive stats.
- Increasing vision control is just good.

TLDR: Poke people with Demacian Standard. Trap people with Cataclysm.

Martial Cadence
- The bonus damage is on CURRENT health, so attacking higher hp targets to push would be your priority when pushing a minion wave, and only needing to attack each one once for maximum efficiency.
- Outside of laning phase and pushing waves, this won't do too much as you'll be too squishy to use it often.

Dragon Strike
- Try not to use this too much during laning phase as you will run out of mana, and this will not do as much damage as Demacian Standard since you have AP for adaptive force from your runes and Spellthief's Edge
- But if you have ample mana, then you can use this as an additional poke tool, but you'll likely sacrafice some hp for it too so you can get into range to hit them.
- At max rank, you can actually use Dragon Strike twice on the same Demacian Standard cast. This allows you to E-Q-R-Zhonyas-Q. So you can start a fight from a very long distance, but since you'll also be pretty deep, only do this when you know you can get back out after using Zhonya's Hourglass

Golden Aegis
- This is a very mediocre ability, and you only put 1 point into it at either level 3 or level 4.
- The shield is small and the slow is very weak. Use it when you have a lot of mana, otherwise you're likely better to hold your mana to keep using Dragon Strike or Demacian Standard

Demacian Standard
- This is your main poke tool in lane phase, and it actually has high base damage, on top of a high ap ratio. Pick your target in laning phase, and keep using it on that target.
- Since you've likely taken Summon Aery, the AoE of the attack speed boost is actually massive, and Summon Aery procs every 2 seconds for your laning partner. So even if you only use Demacian Standard in lane and do nothing else, you're still shielding your lane partner AND giving them attack speed to trade.
- This is a very good scouting tool as well, and grants quite a lot of vision from a fairly safe range.
- Using this to get attack speed and clearing wards is nice too, but be careful if there's nearby enemies who could jump you. In this case, putting Demacian Standard towards your escape path is a safe option, incase someone does suddenly appear, you can dash away with Dragon Strike.
- This effect lasts a solid 8 seconds and is very handy in providing a strong leash, and even speed up objective/tower taking. You can always throw it into your direction of escape, while still providing everyone around you the attack speed incase you get engaged on.
- There's also a lot of hidden power, in that, constantly using Demacian Standard to poke makes it hard to tell for your enemies, if YOUR jungler is nearby ready to gank.

Cataclysm
- Keep track of Flash on immobile champs and you're going to ruin their day. The cast range of this is actually quite far, so you can just Cataclysm a flash-less target, and E-Q out, and let your team kill them.
- Most of the time, after your target dies, it's best to get rid of the cage so that your team can get through, or allowing yourself to escape.

TLDR: You have one rune page. Everything else doesn't fit what you want to do.

Sorcery

Summon Aery
- For each time you cast Demacian Standard, Summon Aery will activate 3 times.
- Adds additional poke, on top of shielding your lane partner twice, for each Demacian Standard cast.

Manaflow Band
- Easy to stack and lets you have a mana pool to scout and get around the map quicker.

Transcendence
- Can't go wrong with more ability haste

Absolute Focus
- More potent poke, but falls off after laning phase.

Scorch
- More potent poke and add a nice amount of damage with Summon Aery

Inspiration

Biscuit Delivery
- Just gives enough mana back early to keep up poke, on top of adding more mana for mid/late game scouting/map movement.

Cosmic Insight
- You'll end up with a lot of actives, such as Zhonya's Hourglass Redemption Locket of the Iron Solari as well as your trinkets, so this will help a lot, as well as being able to Flash Cataclysm someone and then E-Q out.

TLDR: Demacian Standard placement is very important, don't die using Cataclysm

Laning Phase/Early game

- Pick your target (usually the adc), and keep using Demacian Standard on them, on cooldown. If that target completely runs away from you, then aim at the other guy. Preferably the enemy that has less potions/sustain so you can shove them out of lane or put them into kill threat range.
- If you end up getting a kill or assist early, you can look to pick-up a Dark Seal and Amplifying Tome for additional poke damage and be even more obnoxious.
- If you're doing well, you can keep putting points into Demacian Standard and build a bit of AP first, otherwise, start building towards your tank items.

Mid/Late game

- By this time, if there are 3 or more people attacking you at once, you're probably going to die very quickly, unless you have 3+ full items or something. So your game plan shifts from poking people with Demacian Standard to starting a fight off with Cataclysm and then E-Q out.
- Cataclysm range is quite far, so try to use this from brush or a flank so that when you do start the fight, you have an extra moment to E-Q and hopefully not die.
- If you have Zhonya's Hourglass, you can E-Q, then Cataclysm, use Zhonya's Hourglass and then Q back to your Demacian Standard since it lasts 8 seconds.
- This is where keeping track of Flash timers becomes extremely beneficial. Using Cataclysm on targets that can't get out of the ult, essentially lock them there for 3.5 seconds so that your team can clean up.
- In the middle of team fights, it may be better to just Cataclysm whoever's in front then E-Q out. Just be very careful of the enemy follow up when you go in, because you'll be under-leveled with a relatively squishy build.

Grading Explanation below the lists! Check the RANK too!

- J4 has some interesting use cases, especially in draft, and ends up being pretty funny in the way he's played the whole game.

13.9 Plat and Below

13.9 Diamond+

Tier List Grading Points

- Winrates
- Champion Difficulty (more relevant in platinum and below)
- Counter-play (more relevant in platinum and below)
- Flex pick for draft (more relevant in diamond+)
- Early game (more relevant in diamond+)
- Late game/scaling (more relevant in platinum and below)

Overall Points:

- Games last longer the lower in elo you go. Therefore, mage supports tend to do much better since you can buy your items, and you basically become another carry threat. This leads to enchanters/engage being weaker in lower level play since you would rely on your teammtes more often.

- Champions that are fundamentally easier to execute on will have higher win rates. Since it is more unlikely players are pilot-ing their champion runes/builds/kit efficiently, the easier the champion, the more likely to maximize their kits. This is especially apparent in Platinum and below.

- I would recommend playing any of the champs in S+, S, or A. However you can climb on almost anything, provided you always look to maximize your champion kit, mechanics, and impact on the game. Winning is the result of improving.
