Banned deucer.
With the exception of Conkeldurr (Which was OHKO'd by Togekiss), that Darmanitan single handedly took out my team, all with OHKOs. I think it should be banned. Base 95 speed isn't that bad, and combine a very powerful Physical fire move with 140 base attack, and STAB, and it will OHKO EVERYTHING. Also, Why was it UU last gen? http://replay.pokemonshowdown.com/frost-ou-263809
