Perhaps I'm the only one who goes "Cool, a deck of killing my own cards."? I mean, it's an epic concept, and I'd much rather get owned by a swarm of metal bugs then a giant fire dragon(Which is banned in the VGC cups lol).
I mean, if a player can pull off the skills to pound a deck with just a bunch of ants, I think they deserve to go to top cut, rather then just Blue Flaring/Lightning Bolting everything in sight until nothing's left. What's broken again? Having a big Samurott/Serperior/any other giant Stage 2 up just to be OHKO'd by a giant electric dragon thing that decided to pick off all your poor little babies first with a net that we call Catcher, or a bunch of ants eating your cards?
I'm thinking that the giant dragons are a TINY bit worse then the ants. But, where's their hate threads? Oh yeah, nonexistant. If you folks love complaining, pick something that is at least borderline slightly bad.
SoTG isn't broken by ants. It's broken by people who can't accept the fact of being beaten up by a swarm of ants. If you really want to counter it, go get a Heatmor. It eats them in-game, maybe that'll help ya out here in the TCG world.
