Altar of Deadly Spoils

{x}{b}{g}: Target creature you control gets +X/+0
until end of turn. Then it fights up to one
creature you don't control.
Whenever a non-token creature dies, create a 1/1
green Saproling creature token. If you didn't
control that creature, it's controller creates a 1/1
green Saproling creature token as well.
