Gamer girls are indeed awesome. I married one
Anyhow, I've been messing around with more weapons, and I wanted to update on a few things I said earlier.
-Apparently my memory on how the Trap Gun works was horribly inaccurate. What the gun actually does is shoot bullets that don't go anywhere, and the little pellets just hover in front of you. THEN they fire at the enemy after a few seconds pass. So basically, it's like shooting with a long delay. Generally you have enough time to shoot three burst before the first one activates, or enough time to get around to the other side of your opponent.
-I found the Claw Gun, for some reason in Arena they changed the name to Catch Gun. I could see this working like Link's clawshot.
-As a possible alternative for the jet mode (in case I can convince anyone to my PoV), there's the Acrobat Bomb/Pod (they're basically the same thing). Instead of firing out, it makes a large explosion under your feet (even in midair) that launches you upwards. In CRA, hitting an enemy with the explosion launches them in the exact same manner, but I see no reason why it can't just hurt enemies instead in Smash.
