Malphite vs Vayne Counter Pick

60.9% over 1,565 games on patch 16.13.1 is a wide margin by any standard, and the cause is structural rather than situational. Vayne carries 550 base health against 665 and reaches only 2,301 at level 18 while Malphite hits 2,433 with markedly better armor, 124.2 against her 101.2. Silver Bolts is her equaliser, since every third hit on the same target deals a percentage of maximum health and ignores that stat lead completely, and Condemn knocks Malphite back and stuns him against terrain.

Both tools require her to survive the approach, which is the part she rarely manages:

• Unstoppable Force covers a long distance and knocks up on arrival; Tumble is a short reposition, not an escape from an airborne state.
• Ground Slam reduces attack speed, and every piece of her damage is attack-based.
• Seismic Shard steals move speed for three seconds, cancelling the Night Hunter bonus she gains when moving toward enemies.

Final Hour grants extra attack damage and invisibility during Tumble, so a Vayne who reaches her ultimate with items intact still threatens a 2 difficulty tank. Preventing that is the entire plan, and her 330 move speed against his 335 means she cannot simply walk out of the setup either. She is rated 8 for mechanical demand, and the margin she needs on every Condemn angle is the practical reason the gap runs this wide.
