Why Gwen is favored
Gwen's health-based magic damage and healing let her trade through Malphite's armor-focused defenses, then outscale him if she avoids his level-six burst. Her Hallowed Mist(W) also denies Malphite's targeted Q poke while she remains outside it.
How to play as Gwen
Prioritize farm and preserve enough health to survive Malphite's level-six R burst; if he commits and misses, use that cooldown window to trade or push.
A Thousand Cuts(P) adds magic damage based on the target's health and heals Gwen against champions, so Malphite's armor does not blunt her main sustained damage.
Hallowed Mist(W) prevents enemies outside it from targeting her, which can stop Malphite's Seismic Shard(Q) while Gwen stays inside the mist.
How to play as Malphite
Do not spend Q into Gwen's W from outside the mist; wait until she leaves it or enter its edge before using targeted damage.
