Imp's mischief failures to change valid targets.
Imp's Mischief failed to change Wolf strike targets. and removed my commander because of it. I have ran into this problem a few times with other spells. I have valid mana and there was nothing on the board able to prevent this.

All changed targets must still be legal for the spell/ability. So the first target of Wolf Strike has to be a creatrure under that spell's controller's control, the second target must be a creature that player does not control. If your only creature was your commander, then your commander has to be the receiving creature. If your opponent has multiple creatures, the best Imp's Mischief can accomplish is to change which creature deals the damage.
