Farmhand Westley

Lumbering (Whenever it becomes tapped, put a stun counter on it.)
At the beginning of combat on your turn, create a 0/1 beast creature token named cow. Then, if you have ten or more cows on the battlefield, create King Asterion, a legendary 3/24 white Beast Noble creature token with ward 3 and whenever a creature deals combat damage to Asterion, put a stun counter on that creature.
