Educing Gestation

Choose target opponent. Create an X/X blue, green, and black Ooze token, where "X" is the total number of creatures with different names that opponent controls. Then choose up to two creatures the targeted opponent controls. The created Ooze token gains all abilities that the chosen creatures have.
No two poly-beasts are the same. They hatch and evolve to the ecosystem of the chosen world and grow to become the apex predator.
