 * Mario Circuit: Forgot about that
 * Pilot Wings: Lylat Cruise also tilts, and it was legal in Brawl
 * Skyloft and Wuhu: Are essentially similar to Delfino Plaza, which was legal in Brawl.
 * Woolly World: You are right there
 * Castle Siege: Legal in Brawl
 * Congo Jungle: Legal in 64 and Melee
 * Halberd: Legal in Brawl, though I see your point
 * Luigi's Mansion: Counterpick in Brawl
 * Lylat Cruise: See above
 * Pokemon Stadium 2: Legal in Brawl.

So basically for past stages I just looked at whether they were legal in previous games or not
