Sorry, just now coming back to this. I'm surprised that some would think such a situational card would be so powerful. It's only a "battle winner" if you have initiative against exactly two humans of the same gender. So its only going to be useful against banding chains, and in those cases it only takes 2 links out of the chain. I think such a card would be needed now as the last few sets have encouraged banding heroes (TGT, Disciples, Samuel/Royalty, etc.). And it doesn't remove them from the game, so they are easily healed or returned with cards like Brass Serpent promo, COF, etc.
Anyway, thank you all for the input.
