After seeing what can/can't be done in brawl thanks to Damian I have decided I need to test my own stuff again to see if it is valid. Let us proceed. I'll be nice and use an unevolved Bakugan. (I might summon Helios for fun)
Gate card, set! Bakugan brawl! Kaari 'Dark Incanter'- Power Windup!!
Special ability activate! Aeroblitz! Pyrus Titanium Dragonoid enters the field at 500G. Reptak and Titanium Dragonoid gain 100G for each ability card previously played in the entire battle. Me: 700+ 500 + 300 + 300 = 1800 You: 900
Okay, it appears you have already used this effect a few moments ago. And this is one-time use effect per round. Also, it was a Red-class effect and you already used one- you need to evolve more to use more than one Red.
