Well, after a few failed analysises in UU, I've decided to venture to OU. I've really thought hard on this one, and I think I've come to a good one, well, mostly. Some problems with Steel types, but I felt like I shoulf give it a shot.

[SET]
name: Swords Dance SubSalac
move 1: Substitute
move 2: Swords Dance
move 3: Endeavor
move 4: Seed Bomb
item: Salac Berry
nature: Adamant/Jolly
evs: 252 Atk/4 SpD/ 252 Spe
Why this set deserves to be on-site:
-Unexpected
-Seed Bomb is a great physical STAB
-Endeavor should bring foes resistant to Seed Bomb to very low HP, then Seed Bomb can pick them off
-100/100/100 bulk
-100 Atk
-100 Spe
Additional Comments:
-I suppose Zen Headbutt could be used for Infernape of something
Teammates:
-Something to take priority which this thing hates
-No Tyranitar, Hippowdon, or Abomasnow. That kinda stuff kills it, but you should probably know that.
Counters:
-Sandstorm or Hail
-Priority users like Infernape and Scizor
-Gengar resists Seed Bomb and is immune to Endeavor.
I just realized this is pretty short, do you need anything else?
