Obuun, Mul Daya Ancestor
Legendary Creature — Elf Spirit
At the beginning of combat on your turn, up to one target land you control becomes an X/X Elemental creature with trample and haste until end of turn, where X is Obuun's power. It's still a land.
Landfall — Whenever a land enters the battlefield under your control, put a +1/+1 counter on target creature.
