This is my first deck I have attempted to make, and I am on a budget.
The basic idea is: Wipe out the enemy as fast as possible using the energy acceleration provided by Blastoise's deluge ability, that allows you to attach as many water energies as you want per turn. This will allow for a quick setup. Also, Xerneas' Geomancy, that attaches fairy energies to benched Pokemon, will prove useful in energy acceleration. The main thing I need help with is the trainer card section.
The whole deck revolves around using draw cards -- like Ultra Ball -- to get a Blastoise and water Energies out ASAP. I like to use Keldeo-EX as a sweeper with all those Water Energies, but Blastoise is good too.
Once again, this is my first deck and I am on a budget, but I do have a friend with a lot of different Trainer cards, so anything you suggest I can probably get, regarding Trainer cards.
I would also like to note that I went through a lot to get M Kangaskhan-EX, Keldeo-EX, and those Blastoise. I would prefer to keep them in my deck. I also have Victini-EX, Shaymin-EX, Darkrai-EX, and Black or White Kyreum-EX(Can't remember which one)
