Yay, another M:tG player.
Heh yeah, in response to question 4, maybe penguins used to have Flight enchanted on it, but then it was disenchanted.
Man, I have a crazy idea for a deck, but I'm not sure how well it would work. It'd basically be a Mess With Your Opponent's Cards deck. Basically it'd have Psychic Venom, cards like Immobilizing Ink, maybe Confiscate or something like it, and other annoying cards. No creatures.
