Blastoise has problems with RayEels, Garbodor, and Klingklang.
Klingklang has problems with Garbodor, RayEels, and Victini in general.
RayEels has problems with Landorus, Garbodor, and Darkrai.
Darkrai has problems with Landorus, Garbodor, Klingklang, and sometimes Blastoise.
Big Basics has problems with Klingklang, Blastoise, and Empoleon RayEels when set up
Garbodor has problems with Big Basics and Blastoise w/ heavy scrapper
Is that the format?
fun.
So Klingklang, Big Basics, Blastoise with average amount of scrapper (lol) and Garbo seem like good plays.
And your right, Machamp, but it still is a solid deck, why it didn't succeed is either because less people played it or more people were playing scrapper.
