We could try it in a white aggro deck, splashing black: Creatures (26) 2 Anafenza, Kin-Tree Spirit 1 Dragon Hunter 3 Kytheon, Hero of Akros 4 Consul's Lieutenant 4 Lantern Scout 4 Expedition Envoy 4 Thalia's Lieutenant 4 Town Gossipmonger Lands (22) Spells (12) While the interaction between Incited Rabble and Behind the Scenes is cute (anything back-heavy doesnt die to one-on-one combat, typically) and Behind the Scenes would do good work for breaking standoffs, this list looks like it would be substantially improved by cutting the four black cards for some Archangel Avacyns, Archangel of Tithes, and/or Gideon, Allies of Zendikar
They are: 5 * Ivysaur Sticker, 1* Nanab Berry, 1 * Hyper Potion 5* Charmeleon Sticker, 1 Razz Berry, 1 Revive 5 Wartortle Sticker, 1 Pinap Berry, 1 Super Potion 5 Blissey Sticker, 1 Golden Razz Berry, 1 Charged TM 5 Meltan Sticker, 1 Pinap Berry, 1 Fast TM 5 Pikachu Sticker, 1 Rare Candy TCG Shirt & Hat 1 Egg Incubator
A genuine error card is only considered unique when it has been proven to be an original product
A card that looks "shifted" to one side will lose points here, even if everything else is perfect
