Well, I actually have a non-Standard deck myself. I suppose it could be considered Legacy? It's a Dragon EDH deck. I used to have an Extended Affinity deck a couple of months ago.
@Silk: I saw both of those cards pulled at the Pre-Release. Although Precursor Golem's second effect seems like it could be both a help and a hindrance, depending on the situation.
I'm also thinking of adding this card to my Myr deck.
