Dominated Troll

{b}: Regenerate Dominated Troll

{1}{b}, Pay 2 life: You may sacrifice a nonlegendary
Goblin creature you or your opponent controls with converted mana cost/mana value 2 or less or a
Goblin token. If you do, Dominated Troll gets

Keep him well-fed with a regular diet of goblin runts.
He'll be your obedient hulk in no time.
