After a few days of practice on some stages, I have a few things to report/predict for the banlist:
-Pilotwings: The rock outcropping gives ample warning time; Pilotwings will make CP.
-Kalos Pokemon League: Dead, but I was the only one who thought it had a chance anyway, so meh.
-Kongo Jungle 64: It may be even easier to camp on it now. Dead.
-Big Battlefield: Can confirm that my ramblings on BB circle camping was just Roy PTSD; I'd say neutral, but maybe CP depending on how the people who matter think about it.
-Jungle Hi-jinx: As if any sane, rational being thought it would be anything but #BANNED, well, it's #BANNED. Even with cooldown, it's hilariously easy to camp on it.
-Duck Hunt: Probably gonna be CP, but I could see it swinging in any direction, maybe even on a per-event basis.
-Delfino Plaza: No infinite chain-grabs, so we're back in business! Brawl glory days, here we come!
-Halbred: CP again.
-Castle Seige: Mostly depends on your TO. I see it being mostly neutral, though.
-Any Stupid-Ass Boss Stage: Only in Washington. Shine on you crazy diamonds.
-Windy Hill Zone: Maybe in 4v4, but way too big for 1v1 or 2v2.
