Post-rot Super Damage. This is amazing!

Start out with Cressilia to get energy into play, then quickly use Unown VSTAR's VSTAR Power to make your opponent's Pokémon weak to Psychic.

Then, attach Supereffective Glasses (for 3X weakness!) to a Shadow Rider Calyrex VMAX to do 30+ 90 damage for each Psychic Energy attached to all of your Pokémon (using Max Geist)

3 Psychic energy (the attack's cost) = 300 damage

5 Psychic energy = 480 damage!

15 Psychic energy (the max possible) = 1380 damage!

MAKE SURE UNOWN VSTAR DOESN'T DIE, HOWEVER

MAKE SURE UNOWN VSTAR DOESN'T DIE, HOWEVER

Mewtwo does 540 if your opponent has 3 or fewer prize cards remaining, and accelerates energy out of the discard.

Don't forget Shady Stamp (Unown V's attack) if you have one prize card left for an instant win!

Also, just for fun, you can use Unown VSTAR's primary attack to flip 3 coins, and do 210 damage for each heads! Still, Max Geist is much more advisable.

Pumkaboo and Old Cemetary to kick out Path to the Peak (Astral Radiance).
