X-MEN vs JLA
When JLA came out, my friend want to see what would happen if the JLA palyed against the X-men. Well, we know now. I know DC isn't that great, but it was fun.  My X-Men team smoked them. We each had 5 payers in the front line and 2 in the reserve with 12 cards in each battle. We also didn't have events or missions, just a free-of-all. to build the team it was a total of  133 points (19*7=133). It was fun- well maybe for me. I don't think we made a limit on the number of cards in each others deck, but I think it was doubled. My friend has mentioned that he would like to have a Avengers vs JLA, but I don't think this will happen. I think a X-Men vs Avengers should happen soon.

With Events, but no Missions
Usually, my friends play with no missions and events, but one friend wanted to have events and no missions.  Its a very interesting way to play- you still don't have to have a big strategy with the missions, but a different kind of strategy. I think its more fun than a free-for-all- well its still a free-for-all, but with a twist. The rest of the rules are the same.
