Regenerated X-Men
If you happen to lose any of your X-Men during a battle, they all can be restored. This works well when all you have left of a team is Colossus. Go into practice mode and start a game. Then, whenever you want, you can leave and get the wounded X-Men back by pressing A + B + Start. You can then go back and play any levels that you have not completed with a full load of X-Men.
