I've been using a quickstand setup in the corner recently with some success.
b13, trait, ORmb, d2, j2, d2.
f3, d2, CRP, b13, trait, mb lm, ji2, d2.
The setup is easy to see coming but you have a few options to follow up with. A couple examples, You can cancel d2 into close rocket power which can blow up some wakeups and trade with others but some will beat it, if they block your safe. The downside is you're committed to the CRP as you can't block before they wakeup. Also you could mb f3 after the d2 to remain safe but if they block instead of waking up then you waste a meter.
If the CRP hits it pops them into the air for another combo so you could do something like this:
b13, trait, ORmb, d2, j2, d2, CRP. 29%. The rocket power is canceled from the d2 but if it hits it's damage is not added to the previous combo, it starts the second combo. Then ji2, 22, ORmb, b23, lm, 223. 45% So if it works that's 74% for 2 bars.
Just a couple examples of how you can do this setup in the corner and for less meter.
