Probably the really degenerate stuff like Mystic Mine, Agarpain, Spinny, Galatea, and Redoer.
But right now I don't think I really want anything banned. I actually want some things unbanned like Inzektor Dragonfly, Pot of Avarice, Maxx "C", Fairy Tail - Snow, Performage Plushfire, Performapal Monkeyboard, Performapal Skullcrobat Joker, Zoodiac Broadbull, Book of Moon, Divine Wind of Mist Valley, Evigishki Gustkraken, Evigishki Mind Augus, Monster Gate, Infernity Launcher, Genex Ally Birdman, One Day of Peace, Draco Face-Off, and Qliphort Scout.
