Then there's Gift Wrapped, a bunch of cards with abstract art that's meant to resemble Christmas wrapping paper
Pre-orders would probably begin around $300, but the card is a one-of in one good Legacy deck, one medium Legacy deck, and two fringe Vintage decks
The artwork looks like poop, and the effect involves you throwing cards around
It does require a bit of setup, as you need it to have ten charge counters to turn on its effect to deal 100 damage to a creature
Not only can we immediately upgrade the mana base, but also, now that surveil is an evergreen mechanic, we get more surveil cards all the time (just see the Murders at Karlov Manor surveil lands), which means the deck should continue to improve little by little, set by set
