How are you? You new? If you are the basics of this game is to fight bosses and get cards and cash! You can use the Gold to get packs to get more cards! Cards are single-use. If you see a number beside your card, like a Dirt 0, it’s the amplifier! Say for example a Rock 4, it’s a normal Rock card, but amplified 4 times! The amplifier doubles, triples, 4x or whatever number your damage! I love packs, but they only give you around 5 cards.
