Amazing Card game. If you're looking for a light and multiplayer(more then 2) conflict card game, look no further.
It scratches the deck building itch(just barely, but it does!) with its shuffle building mechanic, while at the same time its simple enough to pick up in a few minutes. The cool theme is also amazing. *EVERYTHING* is smash up's theme, from zombies, to robots, to dinosaurs to aliens(and thats only the base set! expansions adds things such as kitty kats, dragons and sharks!)
Be warned though, this game requires a lot of shuffling and resorting of cards, which, while the cards themselves are designed in such a way to make this an easy process, it does mean I def recommend SLEEVEING the game,
