Icons printed on cards are used in conjunction with the icons printed on the bases of playing pieces (ships, vehicles, or creatures referred to as units) in the game. When a unit in a battle has an Icon in common with the combat card played with that unit, it receives the ability from that card. Units with green Match Icons benefit from card abilities with matching green icons. Units with silver Power Match Icons benefit from card abilities with matching silver icons, yet gain other special persistent abilities during game play as well. Gold Wild Icons grant abilities to a variety of units, such as those with a certain number of build stars.
