foil cards mtg I'm not sure how I feel about the mana treatment Until your next turn Of One Mind FOIL ,

Yes, there are builds where you can stock your graveyard up, but Im thinking you could reanimate this blue creature with something like Unearth or Helping Hand, or play it in a tempo build and cheat it in without casting with something like Collected Company

The printing process is so advanced today that a fake card can pass off easily as a real one

not even Keith has seen every single one
