MAXUS BAKUGAN: If you are attempting to create the Maxus Dragonoid or Maxus Helios bakugan using the Pyrus Ultimate, SubTerra Ultimate, Haos Ultimate, Darkus Ultimate, Aquos Ultimate, and Ventus Ultimate cards, think again. It's not that easy.
Fortunately for you, these Ultimate cards do not count as your card chances and cannot be neutralized in any way (no Bakugan effects, no Gates, no Abiities, no Special Abilities, and no Fusion Abilities). However, they also cannot be activated all in one turn. Each card has its own trigger requirement to activate them. Here are the basics.
DARKUS ULTIMATE: Activate ONLY if you currently have one Bakugan/Trap in the battle. No more, no less. (You are able to add more bakugan/traps to the battle AFTER this card is activated.)
VENTUS ULTIMATE: Activate ONLY after you have increased your power level this turn. (A power level transfer works both for this requirement, and the following requirement)
SUBTERRA ULTIMATE: Activate ONLY after you have decreased your opponent's power level this turn. (A power level transfer works both for this requirement, and the previous requirement)
AQUOS ULTIMATE: Activate ONLY after you have negated your opponent's Gate card, Ability card, Special Ability card, or Fusion Ability card this turn.
HAOS ULTIMATE: Activate ONLY after you have lost in a Bakugan battle this game.
PYRUS ULTIMATE: Activate ONLY after you have won a Bakugan battle this game.
Clearly, only the best of the best are able to summon the Maxus bakugan successfully. It tests your knowledge on every aspect in brawling, and moreover demonstrates your skill in battle. Not easy to survive and fill every one of these requirements simultaneously. Logically, the effects activated from these cards last eternally, or throughout the whole game. If you lose and win a battle with them active, and have them deactivate after said battle, you could never summon the Maxus bakugan that way. Lastly, these cards can be activated in any order, and you will still create the Maxus bakugan, so long as each Ultimate attributed card is active.
I hope this is all clear to everyone, as it is rather complex compared to all the other card effects. Succeed, and you can create the two most powerful bakugan in history. Good luck.
