How to play as Master Yi

Expect Malphite's Comet and Seismic Shard(Q) poke to make repeated trades costly; use Alpha Strike(Q) to dodge Unstoppable Force(R).

Apply lane pressure early where you have the chance; once lane ends, target the backline instead of spending time chasing Malphite in mid-to-late fights. (Unverified: no source confirms this note.)

Alpha Strike(Q) makes Yi untargetable during its dash and can avoid the knock-up from Malphite's Unstoppable Force(R) when timed before impact.

How to play as Malphite

Poke with Seismic Shard(Q) instead of forcing repeated all-ins, and hold Unstoppable Force(R) until Yi has spent Alpha Strike(Q); otherwise he can dodge the knock-up.
