SMASH UP

Smash Up Game: Smash Up: The "shufflebuilding" game Smash Up starts with
a simple premise: Take the twenty-card decks of two factions, shuffle
them into a forty-card deck, then compete to smash more Bases than your
opponents! Each faction brings a different game mechanism into play
pirates move cards, zombies bring cards back from the discard pile,
dinosaurs have huge power and every combination of factions brings a
different play experience. During play, Base cards (each with their own
difficulties and abilities) are in play. You attempt to have the most
power on the Base from your minions when the Base is smashed. With
eight different factions, Smash Up includes dozens of combinations to
try.
