Kros, Defense Contractor

Legendary Creature — Cat Advisor — {1}{G}{W}{U}

At the beginning of your upkeep, put a shield counter on target creature an opponent controls. Whenever you put one or more counters on a creature you don't control, tap that creature and goad it. It gains trample until your next turn. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)
