Sorcery — Glitch
Create a creature token as a copy of any creature card with converted mana cost X, chosen at random.
The magical hacker shall meet his match here! I shall call upon the might of Dragons, Krakens, and even the dreaded... Ancient Ooze?!?
It's very important to remember this is suppose to be an online-only set. As such, the game code could easily pick a random creature card with converted mana cost X, whereas it's fairly impossible in paper magic.
