I think I stopped seeing Undead files after they did a minor nerf on EX CAK.
Don't know about u guys, but I stop packing Max hp hate cards in my file.
So you can keep an eye on Folrart, and take note on whats popular.
Right now I would think return is more of an issue than Max HP hate.
Except Verlaat...who recently got nerfed
Ah... Everything's about MONEY, now that makes much more sense...
