MA and Attractor pretty much guarentee that the battle will be on your card. Overpowering. CS destroys all Bakugan on the field before you roll a Darkus Bakugan. Overpowering.
Well actually you can use attractor to counter itself, once you get moved you can play it and move your opponent onto your card. And what about all those new wind cards coming out? You'd have to ban all of those too. And Magnetic Attack. And Shun's Launcher in a way.Clean Slate is kind of overpowered, but not really. There will only ever be a max of 2 Bakugan on the field if you only set gcs when there are none in the field, so it isn't THAT overpowered, plus you can't bring the card back.
I agree on the Clean Slate opinion.
