It is really fun to know how to bounce the can around with attacks and to know all the angles
If you don't know:
Down tilt is the fastest horizantal movement, but f tilt is fine too
Up tilt launches it straight up and can lead into a bair/fair/uair
Dash attack launches it at a 45 degree angle, which is good against airborne opponents
Bair/fair both hit it horizontally, but the parabola drops pretty quick
Up air isn't great, but it can get the can a little higher and kill/force an airdodge
Down air spikes the can, i never really get the chance to use it offstage, but if the can is near the edge of a platform, you can use dair to get it onto the stage, the first hit gets it in the air and off the platform, and the second hit hits it down to the ground
Nair doesn't have that much knockback, so not a great idea for launching the can with
Smash attacks don't do much knockback either if you're grounded tilts will hit it farther
Down b gunman hits at a 45 degree, although not as far as dash attack
Clay pigeon I don't use that much, but if the can is right next to opponent when the pigeon hits it can combo into the can
I think that's everything, I'm not the best dh player, I'm not in elite or anything, but I Think that knocking the can into players is really fun, and the majority of people out there have very little matchup knowledge and don't know how to play against dh
Oh yeah btw the can is active on frame 1 and can get you out of not true combos
