Raticate does WHAT?
I know that Drifblim from Dragons Exalted attacks for free and have more life, but this little thing needs to hit 1 energy less to 1hko regular Ex'es, and if youre lucky enough to hit the 4th, you can bring down megas like theyre flies.
Definitely have to build this one...
MAYBE, and just MAYBE in a format without nightmarch, but for the most part no. the requirements are too high and the damage ceiling is too low.
the M gardevoir from primal clash is way better than this one, post rotation without aromatisse the deck will lose one of its main cards, but it will...
