Nyu, I have mixed feelings about this one. Frustration is pretty meh since - although it's theoretically 50 damage to a pokémon of your choice - it can be stopped by a single damage counter and it requires you to pool two precious Dark energy cards to boot. The same problem faces Toxic Cloud, unfortunately. Again, it's good for quick KOs but it's very expensive on special energy cards and the HP of this thing isn't that glorious either. *Shrug* 5/10; good for fairly quick KOs, but it lacks the umph to stay in and is a bit too selective about energy. .__.
