Since my main strategy is Baton Pass why not do same thing with this thing.
After stat boost from whatever,
Passing By: Unburden ADAMANT
128HP 252ATK 128SPEED
With Air Balloon it will avoid spikes and T spikes for safety the drill is to get boost and gets hit to Blow the Air Balloon for Unburden usage.
I do same thing with Sceptile with no Speed EV since Sceptile is naturally fast (Tail Glow Pass). The Plus it has Giga Drain which is a bonus for HP recovery while Hitmonlee does not have Drain Punch
