Yeah, I agree with that. Looking at things now, I feel EX Pokemon and Mega Evolution need more support to balance out how powerful evolutions have become recently. Audino EX has been on my radar since 110 damage plus 50 damage snipe is quite strong. Even with my Ho-Oh EX build, the ability to KO Shaymin plus Joltik is very nice so a faster version of that, with more bulk is just too good. I wasn't expecting to see it and was prepared to see Night March and things that beat Night March on stream, which was all I saw and then I heard that a m Audino deck made finals. Also the no VS Seeker tech was a smart choice.
I don't think the deck can be good outside of worlds but who knows but I do want to say I wish people would stop saying all of something is the problem when the problem is normally something smaller.
