In my opinion, we didn't. When we look at the momentum shifters of OU, we see Espeon with Magic Bounce, which alters defensive momentum (Magic Bounce was disallowed), Scizor with his trademark Bullet Punch and U-turn (no usable attack, no priority, the movepool we chose did not include the move at all), Rotom-W's Volt Switch (not in the movepool we chose), Pranksters with paralysis and Encore (Tomohawk gets none of those!).
We really stretched ourselves too thin on this one. Too much obsession over what we didn't want Tomohawk to be, and all he could do in the end was become another generic attacker. Every single team I faced in playtesting was a Drizzle team with a SubRoost Tomohawk. Is that really what you guys wanted? I know that wasn't what I voted for.
