Twilight the trading card. Interesting ability, needs a ton of mana but it's based around her ability to teleport. Telport herself and bad guy away, come back next turn.
totally updated, +1 toughness, super ability costs all 5 colors but just removes a creature outright, two new abilities and doesn't tap creatures anymore.
Updated again: Now has ETB: When TStM comes into play target pony gets +3/+3 until end of turn.
