Interesting list, I'd suggest that fish are generally rated too low. Getting a star or swordfish early can really accelerate your income. But you need to have only fish, if you do the game can be over very early.
I'd put panther in S, it has such utility in most archetypes.
Rhino in a stacking deck can be incredible, I'd say A tier but B is reasonable.
Crab is OK, it can have the risk off not being drawn if your last slot is a middle and it's very replaceable, I'd swap it with Fox. There's almost always a hen out somewhere.
Cool list though, I'd imagine laying out all out took some time too. Thanks
