Echidna's Elder Spawn

Flying, Firebreathing ({r}: This creature gets +1/+0
until end of turn.)
Chimera creatures you control are every creature
type. The same is true for Chimera creature
spells you control and Chimera creature cards
you own that aren't on the battlefield.
Other Birds you control get +1/+1. The same is
true for Cats, Dragons, Goats, and Snakes.
