Gameplay
Legendary Creature — Human Scientist Villain
Trample
Whenever you cast a creature spell with mana value equal to Jackal's power, copy that spell, except the copy isn't legendary. Then put a +1/+1 counter on Jackal. (The copy becomes a token.)
For Professor Miles Warren, all any problem needs is a lot of clones and not a lot of ethics.
