Bakugan Trap is a unique Bakugan that plays in addition to the selected 3 Bakugan. It is played alongside another Bakugan, springing open its square cube shape to reveal a different attribute or G-power. Normal battle rules call for 3 Bakugan plus one trap Bakugan. The “Big Game” rules allow you to choose 2 Bakugan Traps. The Bakugan trap must share the same attribute as the Bakugan in the battle. If an attribute symbol is revealed, then the Bakugan’s attribute is changed accordingly. However, it becomes even more powerful when a G-power is revealed and the Bakugan gains that amount. After the battle, the Trap goes to the used pile and moves back to the un-unsed pile with the other Bakugan after you run out of Bakugan.
