If the target spell or the target creature is an illegal target as Sudden Substitution resolves, the exchange won't happen. If both targets are legal but are both controlled by the same player, the exchange won't happen.

A mana ability is an ability that produces mana, not an ability that costs mana.

In a multiplayer game, if the controller of one of the objects leaves the game after Sudden Substitution resolves, the effect that gave them control of the spell or permanent expires. If the spell is still on the stack, the player who gains control of it this way can't choose new targets for it.
