Grim Flayer (Foil Etched) [Double Masters 2022]

Trample
Whenever Grim Flayer deals combat damage to a player, look at the top three cards of your library. Put any number of them into your graveyard and the rest back on top of your library in any order.
Delirium — Grim Flayer gets +2/+2 as long as there are four or more card types among cards in your graveyard.
