This Is My Domain

Choose one creature you control and one creature
you do not control. Phase both creatures out.
For each turn that the two creatures are phased out, put a +1/+1 counter on the creature you control and a
-1/-1 counter on the creature you do not control.
{3}: phase both creatures back in. They fight each other. Any player may activate this ability.
I looked a little different in the normal in the
normal realm, huh?
