This is marincess post the new support. We still have one more monster to be revealed. I think it will be a link 3 that searches a trap, which, if that is the case, I would cut bubble reef.
The sea nettles help to make rank 4 plays, so I've been tempted on putting in one of the cards in the side deck, which I would cut a blue slug for. The nettles also help give this deck a better grind game that rivals earth machine while also putting up a towers more readily.
Anyway, the deck is not perfect, but is really good and can only get much... much stronger.
