You know Magic had guest artwork and cards in one of their recent sets. I think one card was designed by the creator of Mindcraft. They should have had Midway/Netherrealm make a Planeswalker. The Planeswalker would have been Quan Chi. Afterall, Quan Chi is a planeswalker (free roaming sorcerer) according to MK canon. His casting cost would be 3BB.
