MTG Commander: Modern Horizons 3 Barrowgoyf

Deathtouch, lifelink Barrowgoyf's power is equal to the number of card types among cards in all graveyards and its toughness is equal to that number plus 1. Whenever Barrowgoyf deals combat damage to a player, you may mill that many cards. If you do, you may put a creature card from among them into your hand.
