You might be able to use Rimaku's Surprise, it cancels the effect of the text, but I'm not sure if you can use it on your card.
This is completely irrelevent. I believe (and correct me if I'm wrong) that the uestion might involve swapping your (lets say) 300G power Bakugan's G's with the opponent's 700G then swapping out your Bakugan so that your opponent still has the swapped 300 G-Power while you have whatever Bakugan you just brought out.
Maybe you're right, I just noticed the "escape the effects of the G-Power swapping."
