When I play UU, this gimmick is great.No one else uses it, or at least no one I play does.
Hitmontop @ Life Orb
Trait: Technician
EVs: 252 Atk / 252 HP / 4 Def
Adamant Nature
- Fake Out
- Sucker Punch
- Bullet Punch
- Mach Punch
You know, the gimmick is pretty obvious: all priority. This came from me noticing that Hitmontop has surprisingly great defenses, but most people waste that by giving it speed EVs and not giving him more bulk. Also, Technician boosts 3 out of 4 of these moves, making them all great moves. Mach Punch is the obvious pick, being STAB. Fake Out is a great opening move. Sucker Punch shuts down handelures that think they can come in and easily kill me. Bullet Punch is mostly useless, but helps for neutral coverage. But it gets even better with the next Pokemon.
Umbreon @ Leftovers
Trait: Synchronize
EVs: 252 SpD / 252 HP / 4 Def
Careful Nature
- Curse
- Baton Pass
- Heal Bell
- Foul Play
This guy is made completely to set up the above Hitmontop. You see, the Speed decrease from Curse doesn't matter when your using all priority moves, and Umbreon has great defenses to take hits so it can Curse then Baton Pass. Heal Bell is the obvious cleric move, getting rid of status effects. It's mainly for itself, to take off Toxic and Paralysis. Foul Play is there so it can take care of itself if needed.
Like I said, not many people use these two set ups, which I find weird. They work great together.
