Mew Retreat Blitz

Build up energy for Genome Hacking on Mew in case of strong enemy active attack. Evolve and prepare Pidgeot EX for strong attack when Mew isn’t necessary. Use Snorlax to tank while setting up. Use X Speed and Leaf to move around as needed. Use Sabrina and Pidgeot ability to mess with opponents active Pokémon. Use two different energies in case of psychic matchup so you can stack non-psychic energies for Mewtwo EX counter and not lose psychic energy.

[NOEX] Steel Wind

This deck utilizes Old Amber to guarantee drawing Meltan or Kangaskhan as a starting basic. The goal is to either get an early Amass off, or stack energy with Kanga tanking hits and immediately swapping to Melmetal to sweep. I like Pokedex here because it gives you a better chance at finding an evo if needed by checking your next 3 cards and using a Pokeball to draw a basic + re-shuffle your deck.

Salt Mine

You ever wanna just make your opponent mad? Like, rage inducing in every stage of the game? Well, Fearow and Wigglytuff have got you covered. Is it good? Well, no. Is it fun keeping a MewtwoEX on 1 energy for 2 turns, then KO'ing it with the inferior Kanto bird? Yes, yes it is.
