This deck is kinda archetype of Aromatisse/Big Basics, and Yveltal-decks. But I made this, because Prism Energy aren't playable anymore, so Aromatisse/Big Basics aren't so workable... But now, here's the deck :
Pokemon: 14
Strategy:
Xerneases are loading energy to the game with their Geomancy-named attack, which takes one Fairy Energy from the deck to 2 of your benched pokémon. Aromatisses moves the energies with Fairy Transfer, what Xerneas loaded to the game. Yveltal-EX:s are the main attackers of the deck, along with Seismitoad-EX, which makes Trainer Lock for disturbing opponent's game. Lucario-EX is the counter of the Electric-type pokémons, who are the weakness of Yveltals. Beartics are the Pyroar-counters of deck, because all of the attackers in this deck are Basics, and Aromatisse does too little damage with too big Energy Cost.
