Perrie, the Pulverizer {1}{G}{W}{U}
Legendary Creature — Rhino Soldier
When Perrie 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 Perrie 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.
