Well, that might not be the complete solution. Violent Overswing in its current form appears in the deck of Tvericus, Monkey Chieftains, and Wild Gnomes. (Also Felvin and Lothar Lotharsson.) What then?
I still believe Violent Overswing needs a damage buff or an additional (beneficial) effect. Heck, even Controlled Overswing pales in comparison to Strong Hack/Bludgeon. (Compare Cudgel Of Wrath/Dark Drewg's Mace, The Strongarm/ Mindless Aggression).
Yeh it wouldn't be a complete solution. Can give them all the new version, or an old card with similar art.
