Right, you don't need TGW
This list is starting to look really good
At this point, if you are looking for more things to put in that would make it good, taking out Claydol wouldn't be a bad idea because it is mostly a Stage 1 deck (or at least setting up the combo that the deck is most likely based around) and Tentacruel and Lanturn attack for pretty much 0-1 energy.
