Here are the Critters, a rotating split pile featuring a colorful assortment of woodland creatures.
Raccoon is a Moat that can also give +$1 if there's Copper in the trash, at the cost of junking yourself (those greedy trash bandits can't resist digging through the garbage). As the first card in the split pile, this one rotates the pile, but only when you line it up with a Silver.
Stag is borrowed from another rotating split pile I designed, a VP card that rewards getting all four of them. They're skittish though and rotate the pile whenever you gain one, making it tricky to collect the whole herd of them.
Fox is Duration trasher and draw to X, very sly. On play it can be like a Lab that trashes, pretty nice, but it can't increase handsize beyond 5. Be careful on the duration turn, the trash is mandatory.
Wolf is a Night - Attack that can gain stuff you haven't gained yet, while making opponents discard a card they have duplicates of.
There are some light interactions within the pile: Fox can combat Wolf's handsize attack and will gladly eat the Coppers Raccoon nabs. Stag and Wolf push the pile's variety theme, and Raccoon's Reaction doesn't mind drawing a Wolf.
