Pokemon: 13
Strategy:
This deck acts like the normal M Rayquaza Deck but with cards to counter threats.
Virizion EX: This card is a direct counter to Siesmotoad Decks. It blocks LaserBank and can get more energy onto your Pokemon. It also has low retreat cost and can 2HKO Siesmotoads
Kyurem/Genescet EX/Mr. Mime It depends on your area. Kyurem can be very good against Fire Decks, Donphan, and Landerous EX. Genescet EX can be a decent option as it can OHKO Siesmotoads and can be a threat to Primal Groundon and Kyorgre. Mr. Mime would be good if your area is "a card that attacks bench" heavy
I think you already know what the rest of the techs are for
I chose Robo Sub. over eggs because the oppenent doesn't get a prize card and you or your oppenent can use Trump Card to get it out again
Overall I think this might be the deck I'll use at Spring Regionals but it could still be changed (good thing I got time to think).
