OK, firstly, a fire type with a weakness to itself isn't good!
For the early-game stalling, I'd rather use Skarmory from DS, because it's a metal type and can stall with metal energy(s) and steelwing. also, it allows you to search for any metal pkmn (like delta species).
This thing's first attack is useless, because you wont have any discarded energy in early game and its own attacks dont discard energy. its second attack is too weak to be used as a main force, and 70HP wont last a single turn against most evolved ex's.
So, IMO this card is only good for countering BASIC non-fire type ex's, especially Registeel ex (EM), whose Wide Laser can be a HELL OF A PAIN at early to mid game as it can KO all your benched basics in just a couple of turns. other than that, this card is useless.
