Ventus (Green) – These are the most powerful cards in the game. It is a good strategy to include a card that has the name of your attribute if all your Bakugan have the same attribute (color).

• Pyrus: Before you roll, All Bakugan with printed G-powers are reduced to zero.
• Ventus: Play with your Ventus Bakugan and lets you swap the Gate card from your used pile.
• Aquos: Before start of battle, Replace that Bakugan with any of your unused Bakugan
• Darkus: During battle, if your Darkus Bakugan’s printed G-power is higher than your opponent’s by less than 70, the gate card gives no G-power bonus to your opponent.
• Subterra: After you lose a battle with Subterra by less than 100 G-power, the winning player does not win the gate card. Rather, the Gate card remains in the arena and the Bakugan go their owner’s used piles.
• Haos: During battle, if your opponent’s G-power is 150 or more than yours, Your Bakugan gains G-power based on its attribute.
• Pyrus2: After winning a battle with Pyrus, play. While this card is in your used pile, when your Bakugan gets Gate Attribute bonus, you take highlighted bonus instead of the one from your Bakugan’s attribute.
• Ventus2: Start of battle, if you win battle by at least 150 G-power, put one of your unused Gate cards into the arena in place of the Gate card you just won.
• Aquos2: Start of battle, your opponent must swap out Bakugan with one from his unused pile if possible.
• Darkus2: Play after you battle; when card is in used pile, when your opponent’s Bakugan gets a Gate Attribute bonus, you make him take the highlighted bonus instead of the one from his Bakugan’s Attribute.
• Subterra2: Start of battle, if you win battle by 150 G-power, put one of your unused Gate cards into the arena in place of the Gate card you just won.
• Haos2: Start of battle, if opponent’s G-power is 160 points more than yours, move gate card from your opponent’s used pile to yours.

There are some very unique green cards including one that can put “won” gate cards back into the game and one that can put an opponent’s Bakugan completely out of the game. This rare card is the notorious Doom Card, which also awards an extra bonus for Darkus Bakugan. Specific cards that have the same name of the Bakugan can be awarded very high G-power bonuses under the right circumstances.
