Okay, so basically I made this dumb strategy. Here it is.

Primary : Loose Cannon
Secondary : Any shield (preferably Chargin' Targe, but it doesn't really matter (Splendid Screen if using Stock melee))
Melee : Half-Zatiochi (or stock (or Frying Pan))

The strat is you do a sorta jump with the Loose Cannon by holding Mouse1 untill it goes to the max, and right before it explodes, crouch jump backwards and it will launch you. If you want to do it again, let go of Mouse1 for a very small amount of time, then hold again. If you did your last jump you want to do, turn around really quick, that way you can air strafe. It's kinda like Trolldier, but you're taking damage from jumping, and killing bad guys heals you (unless you're using stock/frying pan). Also, you can Double Donk, of course.

There's different strategies for different shields. Chargin' Targe gives you more resistance to damage, so if you want to die slightly less, use that. Splendid Screen deals more charge damage, so you can use that if you want to kill dudes faster. Tide Turner gives you more mobility, so if you want to have somewhat better escape options, this is the shield for you.

And, the Half-Zatiochi, is used for keeping your health up. Just hope you don't kill your target with the charge. If you don't want to risk damage for healing, you can just use Frying Pan, or stock.

Well, that's the dumb strategy I made up. Also, Red Robot, I hope you enjoy this stupid strategy!
