The misprints can be replaced by contacting Upper Deck or by just playing by the rules as intended.
This would be an excellent addition to VS System - The Alien Battles, although there will be some power balance issues if playing Loyalty Decks from the different sets but these would not be noticable for casual play.
Just a note. All VS System 2PCG products are fully compatible with each other. That means that you can mix Marvel Superheroes with Predators and/or Xenomorphs if you wish.
I'm a big fan of superheroes but I prefer to stay somewhat thematic.
So it would be balanced if I played Aliens deck vs Predators deck?
For multiplayer I can basically play with 4 people in a free for all?
Is it possible to play multiplayer with a single set while feeling 'complete' and satisfactory?
