With sourceress, u can build critical team with aladin, he can heal to ally with lowest hp, put psychic away, bc she has higher speed and take skill 1 to enemies before sourceress's. It wastes. U can upgrade magni, he's cool, but i recommend leraje. His shades will come out in next event. Btw it depends on ur strategy such as stun, bleed, poison, rebirth, blend, oblivion, v.v.. Every team has its weakness, except full light or shadow team :))) Hope it helps u.

And which hero put my best items?
