Uh... Lightning Chidori and E-Tele shot through the roof because of them topping. I dunno about you, but that's a pretty big indicator of something big with them even without me saying it.

Then there's also the issue with power creep and all that. All the Secret Forces archetypes are pretty powerful in their own right. Yosenju bounce like there's no tomorrow, Ritual Beasts dodge effects like they're in the Matrix, and Nekroz... Well, they're Nekroz.

Edit: OH MY GOD I COMPLETELY FORGOT ABOUT PLAYING SYLVANS.
