Nice one, let the record show that Sub-Terra 2 can probably be replaced by Marucho's Launcher, if you'd prefer."PLay before rollling an Aquos bakugan, if there is only one gate card on the field you may set another gate card"The card's idea is generally the same, although with sub-terra being a stronger attribute you may have a better chance with it during your twoon one battle.There are some variables to get around this strategy but I'm not oging to get into that now. Anyways its an awesome counter strategy.
Marucho's Launcher wouldn't be good, because then it would take Brainwashes place. And Brainwash is the key to this strategy. You can't use Attractor or Magnetic Action, because your opponent has to roll and stand. Combo Battle just makes the stand. Not roll. But with Brainwash, it only says that your opponent's Bakugan has to stand. Not roll. So Marucho's Launcher would ruin the counter-attack.
Oh thats right I forgot it was a red card, I'm sure there is some green card out there that has the same effect though...maybe.
