Fantasia Team: Roselia (From Budew), (Mega) Audino, Aurorus (From Amaura), Clefairy, Cherrim (From Cherubi)

Potentially Meloetta since that was from her original storyline (from Pokemon: Nexus - Season 1 *wink wink*) but I don't know if the rule of legendary has changed since then??

Ace Team: Shiny Zorua, (Mega) Houndoom (From Houndour), Misdreavus, Milotic (From Feebas), Luxray (From Shinx), Garchomp (From Gible)

Potentially befriending Jirachi (Like stealing/buying a mysterious purple rock that has Jirachi inside) but once again I don't know the legendary rule??
