If someone made a live-action film of a block from magic (wishful thinking here), first of all, pick a block, and then a character from that block. Who would you want the actor/actress to be for the character you chose?
*I’ll give you two points for this one since it’s a two-parter*
I would pick the Eldrazi block. Character that I would choose would be Gideon, played by Lorenzo Lamas (He can rock the long hair, play brooding characters and kick major booty).
