Nice work. Cloyster is fun to battle, and I would do it more often if it weren't for the fact that, as a T2, it gives lesser rewards than T3's.
Any reason why you are keeping ES on the Exeggutor? It seems like for most of the situations where you'd want to use it, BS would be better.
You have several very strong mons there. I'd be curious what else you have, because I can't help thinking the Alakazam and Rhydon could be improved upon.
But, good job crossing Cloyster off your list.
