Ethereal: Grants 2x it's chips value (encouraging you to put it on higher-value cards) and discards itself when it stays in hand (kinda like Metal cards, but helps indirectly thin the deck slightly)
Appearance: teal-white mix-texture, slight transparency
Mummy/Zombie/Infected: When played, may turn a random other played card into a copy of itself (overwriting that card's enhancement/edition/seal)
Putty: Loses it's rank and suit, copies the rank and suit of a random other card in hand when played (BEFORE hand starts being scored)
Appearance: Brown or Purple putty
Smudge: Next time it's played, it's permanently transformed into a random card. 50% chance to have a random Enhancement and 5% chance to have a random Seal.
Appearance: Center symbols are replaced with a "?"-shaped smudge similar to wildcard.
Dog-eared: If a dog-eared card is in the next 5 (buff/nerf as needed) cards you'll draw, an indicator above your deck will say so
Appearance: Top-right corner is folded over like a dog-eared page in a book
