Trample
Whenever you gain life, you may place a +1/+1
counter on Erdtree Avatar.
At the beginning of your end step, if Erdtree
Avatar has ten or more +1/+1 counters on it,
gain life equal to its toughness.
"A manifestation of the Erdtree's power, these avatars
guard the minor Erdtrees scattered about The Lands Between."
