Deer Note 2 No-P.U.N.K
Banish all "The Planet" cards from your GY, then destroy up to 20 cards in your opponents deck and if you do, half the ATK of your opponents monsters and if your opponent summons monsters, half the ATK of the summoned monsters (These effects last for the rest of this duel)
Im partially doing that so that this doesnt turn into a mash-up of the worst and funniest cards in Magic
Abandon Attachments can fuel a lessons in your graveyard kind of deck, and its the main theme of blue-red in the Avatar set
