Affectionate Indrik (JMP 373)

Creature — Beast • Mana cost: {5}{G} • Jumpstart • Uncommon

When this creature enters, you may have it fight target creature you don't control. (Each deals damage equal to its power to the other.)

The problem isn't the indrik's enthusiasm, it's Ravnica's lack of guardrails.
