The stage that flips around gives huge warning (for like 5 seconds) and does it always in the same wayI never understand why people though all items should be banned no questions asked, but YO STAGES DAT FLIP AROUND AND SHOOT LASERS AND **** AT YOU DAS FINE
items spawn randomly and a few are capable of taking a stock or dealing huge percent if attacked/picked up on spawn
if smash had fixed item spawn locations for each stage I'd be all for a (selective) pro-item ruleset
but that's not the case
