Perrie, the Pulverizer

Legendary Creature — Rhino Soldier

When this enters the battlefield, put a shield counter on target creature. (If it would be dealt damage or destroyed, remove a shield counter from it instead.)

Whenever this attacks, target creature you control gains trample and gets +X/+X until end of turn, where X is the number of different kinds of counters among permanents you control.
