Aquos (blue) – These are the fundamental ability cards which give basic G-power bonuses to your Bakugan. It is VERY important to select specific cards that grant bonuses to your specific Bakugan that you play with. For example, if all your Bakugan are black (Darkus), it makes no sense to equip yourself with the Summon Wave card, which only gives G-power bonuses to red (pyrus) and blue (aquos). Make sure you completely understand the details of the card. For example: The Summon Wave or Brushfire card can only be played on the opponent’s Gate cards where your Bakugan gains an extra 140 G-power based on its attribute. But when you play a card like Mega Impact or Blaze, your Bakugan will gain an extra 80 G-power during battle. There are 50+ different blue ability cards with new ones being released with newer series. Extraordinary cards exist that really change the game up. Special Crush: when you don’t have more Gate cards in your used pile than your opponent, this card gives you G-power based on its attribute to your Bakugan that has a special treatment up to 200 pts!
