I've played a deck for along time now but the rules have now changed. In my wiggly/sneasel deck I like to attach dark energy to wiggly to do 70 damage with do the wave. It's been my deck's strategy ever since I made it. Am I allowed to still do this. Or do nintindo rules prevent this. If so, would I at least be able to use my strategy in unlimited battles? Thanx for any help.
