Primal Might
From Foundations set
Primal Might
Sorcery
Target creature you control gets +X/+X until end of turn. Then it fights up to one target creature you don't control. (Each deals damage equal to its power to the other.)
Rulings
- You can cast Primal Might targeting only the creature you control.
- You can cast Primal Might with 0 as the value of X to just have the two target creatures fight.
- If you choose two target creatures and either target is an illegal target as Primal Might tries to resolve, neither creature will deal or be dealt damage.
- If the creature you control is an illegal target as Primal Might tries to resolve, no creature gets +X/+X. If that creature is a legal target but the creature you don't control isn't, it still gets +X/+X.
