The idea of the deck is to use Mew to build up Rampardos on the bench as your main attacker.
Use Mew to search for your fossils and candies. Use Scoop Up Net and Air Balloon to Reset your Mew to keep spamming Mysterious Tail.
Bibarel and Greninja help speed the deck up and set up your discard pile for Raihan.
Use Raihan to accelerate energy on to your Rampardos. Also grab anything else you might need like Candies or Rampardos.
I run one Galarian Zapdos V for a suprise 1 energy attacker.
