Right now it is overhyped, but thats because the meta-game has way too many good fighting cards, EX. machamp, lucario, gallade, ect. But I think in the future it could be big, or at least better than it is right now. Plus overhyped completely depends on which devision your in. Seniors and Masters not so much, but thats because we can think of better and more reliable ways to get around it but in juniors, where they can't, the card is underhyped.
Plus to who ever is thinking bout the 1-1 Xatu ... what? yeah you go fill 2 pokemon slots for a tech against 1 card.
