TKBreezy said it best.
"What good are the tricks if they aren't taking stocks?"
That being said, those setups were sick and great for a highlight video. I don't expect most of them to work often on players who know about Pac-Man though.
Bthrow -> Melon was impressive and it's the only one I didn't know about that I can see working on consistent basis. It's still risky because it requires grabbing, and it's telegraphed because Pac-Man has a melon in hand. It's still better than nothing though, as people do think SHIELD whenever they feel threatened by Pac-Man and it counters that hard.
Abadango special (Trampoline them into fruit) is classic, but it is telegraphed too and requires you to be on top of them.
Reasons why I don't think the others will work often below.
