Why Malphite is favored

Malphite's targeted Q poke steals movement speed, and Ground Slam(E) cuts attack speed, making it difficult for Vayne to maintain the repeated attacks her damage needs. If he chips her down, Unstoppable Force(R) gives him a reliable all-in threat.

How to play as Malphite

Use Q to chip Vayne and take away her kiting speed; look for R only after the poke has made an all-in realistic.

Seismic Shard(Q) is targeted and steals Vayne's movement speed, so she cannot sidestep the poke and is slowed when trying to kite afterward.

Ground Slam(E) reduces attack speed, which makes it harder for Vayne to complete repeated Silver Bolts(W) attacks.

How to play as Vayne

Avoid extended auto trades while Malphite's E attack-speed debuff is active, and keep enough health to withstand his R engage.
