Consider a deck of cards. If you were design a deck of cards, such that a mythological/fantasy beast (or class of beasts) were each a suit, which four creatures would you use and which suits would they correspond to?

My current thoughts are :

Hearts - unicorn, ki-rin, (pegasus)
Spades - dragons
Diamonds - gryphon/griffin, sphinx, hippogriff, (pegasus)

And I'm completely stumped for Clubs. I couldn't come up with another beast type (humanoid, yes, but that somehow didn't fit).
