Fake Out + Mach Punch
Jolteon - 105% minimum damage
Infernape - 85-100%
Alakazam - 97-100%
Haxorus - 67-80%
Breloom - 85-100%
Garchomp - 52-64%
Venusaur - 50-61%
Keldeo - 62-75%
Now, you cannot tell me the extra damage from Fake Out isn't huge when you are facing a sweep. The perk of using Technitop as a revenge killer is that is the majority of sweepers in OU making the cut (save the obvious Volcarona, Dragonite, Thundurus-T) and he doesn't need a choice item to do it.
For what it's worth, Sucker Punch is kind of meh. It is too predictable and you are better off using Pursuit for those targets (especially if Fake Out takes them low on health). Pursuit and Stone Edge where the only things I've bothered using in the 4th slot. Stone Edge at least keeps Dragonite and Volcarona from getting too greedy.
Those calcs aren't too convincing considering that Jolteon is the only one you can reliably "revenge kill" and no one uses it.
I am not approving Technitop.
