Yhorm the Giant

Trample
Whenever a creature with power 5 or greater
enters the battlefield under your control, Yhorm
deals damage equal to it's power to target creature.
Whenever a spell you control puts a +1/+1
counter on a creature, put a +1/+1 counter on
Yhorm.
"Yhorm is the descendant of an ancient conqueror, but
was asked by the very people once subjugated to lead
them, serving as both a weighty blade and a stone-hard shield."
