STRATEGY:

The deck uses a classic transfer tactic. Use Aromatisse to transfer energies around on the battlefield and heal the attackers with Az and Max Potion. Malamar Ex is used to inflict status conditions with Laser Bank to disable attacks or enable easier on hit knock outs with Xerneas Ex and Yveltal Ex.

Use Hydreigon LTR instead of Aromatisse XY. I know Hydreigon is a Stage 2, but it's worth it. More HP and moves Dark Energy instead of Fairy, meaning that you don't have to run 2 different types of Energy. In addition, you could also run 1 Hydreigon PHF to pull out any D Energy that would get discarded.

Get rid of all the Fairy Types you have in your deck. Also, since you already have Max Potion, AZ is pointless. Toss him. This should leave you with 11 Empty Spaces. Use 3 Deino, 2 Zweilous, 2 Hydreigon LTR, 1 Hydreigon PHF, 2 Rare Candy, and then you can use that last slot for 1 more Max Potion.
