Prototype — 3/3

When Warzone Duplicator enters the battlefield, return target creature an opponent controls with power less than Warzone Duplicator's power to its owner's hand. If that creature wasn't a token, conjure a duplicate of it into your hand. It perpetually gains "You may spend this mana as though it were mana of any color to cast this card we wish we could read the end of, but it got previewed with a scrollbar on the text which is very cool."
