[Squirrelloid]

Worthwhile vanilla pretender chasses (I'm probably missing a few, but these are the ones that jumped out at me):

Wyrm
Gorgon
Cyclops
Prince of Death
Oracle
Fountain
Ghost King
Lich

(Avoiding pretenders who are very nation-specific, although most of those are just bad). So its 8, maybe a couple more i missed. (The dragons are probably perfectly playable, but why you'd choose them over the ridiculously cheap Gorgon or PoD is beyond me).
