Aaattack is a deckbuilder, where you build and customize a bag of magical runes to take into battle against your foes. At the start you will draw 3 random runes from your battle bag and each turn you will draw another one at the end of the turn. You get to play 1 rune per turn (some runes allow you to play more than one rune as follow ups). Your foes will also have their own customized bag of runes. To take back the lands you must clear all foes from the map. Each region of the map has 1 monsters and one boss monster.
