Z CARDZ are special pre-punched cards that can be assembled into 3-D models. Z CARDZ the Game allows you and an opponent to build an army of these Z CARDZ. Through the use of special formation cards, you try to be the first one to KO all of your opponents Z CARDZ. Booster packs contain 5 models and a matching playing card for each model. Pack contents consist of 3 normal models and 2 "special" models, colored in either metallic silver (rare) or metallic gold (ultra-rare). 60 different models are available in booster packs, each having a normal, rare, and ultra-rare version, resulting in a set size of 180 models.
