Smash Bros 20-Hit Combo Achievement(got it)

[Killjoy262]

Has anyone ever gotten at least 20 hits in the training grounds section of SSBU? If so how did you do it and do you have any tips/tricks?

UPDATE: Nvm, simply set the targets Damage % up as high as possible, grab and spam the attack button

You could either throw the Sector B-bomb in training mode or mash the jab combo in between walls.
