Mewtwo Energy Generator

This deck is all about generating energy quickly by using Solgaleo's GX attack (powered by 1 rainbow energy) and Starmie to get the energy out of the deck and straight onto the Mewtwo tags, then using Gardevoir to double it, and then using Mewtwo EX's Scatter Shot to deal insane OHKO damage.

If you do a Sol Burst and add 5 energy, Gardevoir doubles it to counting as 10 energy, which would hit for 300 damage! But, then, if you manage to get even JUST ONE hit off with Starmie and add 3 more, to bring

But, then, if you manage to get even JUST ONE hit off with Starmie and add 3 more, to bring it up to 8, Gardevoir doubles that to 16 which hits for an INSANE 480 damage PER ROUND! off of just 2 rounds of charge up!

You could theoretically make a several other versions of this deck without the Mewtwo tag and just use more Mewtwo EX or even the Mewtwo GX with full burst cards. But I chose Mewtwo tag because with the 270 HP he is MUCH, MUCH harder to OHKO, allowing him to make better use of Damage Change than Mewtwo EX and can soak hits better than Mewtwo GX.

You could also make versions using ADP tag for 3 energy attach per round, but Starmie is MUCH faster to charge up, and only gives up 1 prize card when killed instead of 3. You could also use other Pokemon to do the damage that have attacks that scale off of psychic energy, like Mewtwo EX and Mew V with X-Ball attack, Deoxys EX (ex8-97), Gardevoir (pl1-8), etc, but I felt that this combonation had the best potential for success.
