Ozraptor

Whenever Ozraptor enters the battlefield under your control, It deals X damage to target creature your opponent controls, where X is the number of white creatures you control.
The generic name is derived from "Ozzies", the nickname for Australians, and a Latin raptor, "seizer". The specific name honours a fictional character, the swift-running thief and archer "Subotai" from the movie Conan the Barbarian.
