Maybe we should try hypnotising Unfooruman again. From what I noticed, his Slay and his attack could slack Spotty's HP to approximately 8. Then Shuri and L33tzan would attack Spotty, and thus he would be done... assuming Unfooruman cannot cast Raise, that is.

Then we could try summoning Enchantresphere. Like Boggy has noticed, Unfooruman shouldn't be able to unsummon it back, and thus it would stay on the battlefield until it's dead.
