Possible Strategy

Faction Strength and Weaknesses.

Demacia: Has a ton of front-liners. Has two short ranged AD carries and Lux for ranged champions, however. Break the front line and they're screwed. Good luck with that: Vayne and Quinn are both good duelists. Vayne can stealth and Quinn has her E. YI you aren't going to 1v1 Vayne post level 6 unless you're ahead of her. Or Draven.

Noxus: Has a wide variety of casters but only one AD carry and not many frontliners.

Ionia: Balance(ha) between casters and front liners.

Piltover: We have poke and that's about it. Hooray 3 carries.

Therefore, we should probably run poke-oriented teams, right?

Possible team comps:

Poke #1: Blitzcrank Jungle, Ziggs mid, Jayce top, Ezreal/Caitlyn carry, Support Orianna.
Reasoning: Blitzcrank can jungle fairly well. Ziggs, Jayce, and the AD provide poking power, while Orianna doesn't need farm to AoE cc people. We can NOT just engage fights unless we've poked them down first. If they try to hard engage, we can Jayce gate + Orianna speed boost away, while still poking them. If they're...special...enough to chase us, Blitz pulls someone and we kill them. I hope.

POKE.

Generic In-Case-We-Can't-Poke-For-Some-Reason: Jayce top, Vi jungle, Ezreal/Corki/Caitlyn carry, Blitzcrank support, Orianna mid.
