Spined Tyrranax

Creature — Dinosaur Beast

At the beginning of combat on your turn, you may pay . When you do, put a +1/+1 counter on target creature. That creature gains trample until end of turn. (It can deal excess combat damage to the player or planeswalker it's attacking.)

"Drive the beasts into the enemy ranks, then stay back and let them do the work." —Koth
