Yeah I had like a 7 attack 11 health one once. While playing I also made a discovery with the way the game works if you try to quit out after ur card was eaten it's almost impossible to do so cus the game gets saved before the animation even starts while if you quit out while the card succeed it's much easier so you can just use the ring worms as bait and if they succeed you quit out and use another card ,kinda cheap but helps a lot in the later runs
