Roli, Dachs

Flying, deathtouch, lifelink, indestructible, haste
Landfall—Whenever a land enters the battlefield
under your control, put a +1/+1 counter on each creature you control.
Whenever a creature you control mutates, create
a token that's a copy of that creature.
Roli Dachs assigns combat damage equal to its toughness rather than its power.
