To avoid the fact that as someone already said the game doesn't need OP gamebreaking creatures, you may win those, as pets from the oracle.
do you mean as in 3 game pets, or as in, like nymphs only obtainable from oracle? personaly i'd like to see them as normal cards if they ever get into the game (unlikely as it is i'd be happy if that was the case) but they need heavy balancing now
