although i don't like you that much, lemme see. Any stage like Halberd/Delfino's plaza are really good, you can attack them from under the stage w/ all his multiple jumps. And of course anything w/ a walk off stage (BoE, and uh, is just not even fair, just cg and when you both get off the map, fthrow and they're dead. Anything w/ a wall, but idk if corneria is allowed, but uh, shadow moses island is very good, just don't counterpick it if they are fox or marth or GaW or something, cuz they're faster than you and can also wall infinite. Then break the pillars if you've got some time after a kill and go for the gimp kill CG style like i was talking about on walkoff stages. I would say PS1, but it doesn't have much room for teh CG personally, but it does have a wall on one of the terrain changes so.
