ideas:
A: SBD edgegaurd.
Near ledge:
1) Jump and Throw banana upwards
2) Up B and upair to catch as you rise
3) throw banana downwards
4) Follow with dair.
result: you create wall of two items against the recovering opponent, followed finally by an attack, which if done right can auto cancel for another attack, or if you aim it, dair and grab the ledge.
Alternate method:
1)grab a banana and grab the ledge.
2) tap back to release and immediately throw the banana upwards.
3)Spring upwards to catch banana.
4) ASAP, drop the naner, fast fall to follow naner
5) attack (bair for example), regrabbing naner at the same time.
you can do something similar on stage as well, you can also add a naner to other setups like Cith combo, something i call Naner-Assisted Setups (NAS)
Cith combo:
1)grab naner, then spinshot
2) quickly as you spinshot, Z drop the naner, because you can't airdodge in the first half of the spinshot, this should be made easier.
3) Spring, facing the direction of the naner.
4) Dair towards the naner
so not only does the opponent have to deal with a falling spring, they have to look at the potentially more dangerous naner falling near by as well, followed by your lagless dair. In some scenarios/ heights, you may be able to recatch the naner as you fall, with an attack
I plan to have a small vid of me doing tricks as I try to make stuff up basically

but this is an idea of what i thought of and what im practicing in my free time.
