"Discards top 3 cards." Better use Mallow, or you are risking cards that could help you. (Rare Candy, Vikavolt, Draw power, etc etc. Might want to use a UPM Oranguru to get your resources back in case you do discard them.
So let's say you set up Vikavolt turn 1. with Rayquaza's ability, you are getting 90 dmg off the bat. Now run Mallow (put two Lightning energy on top), set 2 Rayquaza on bench discarding the energies. That's 2 energies. vikavolt strong charge a Rayquaza (makes it 4 energy) and put another energy for the turn on the other Rayquaza (makes it 5 energies). 30 X 5=150 damage, attach Choice band=180 + Kukui=200 and Devoured Field doing 10 more damage for those one hit KO on Zoroarks and other 210 Pokemon.
If a Rayquaza get's knocked out (3 energy in the discard), you can play Zinnia and attach 2 basic energy to one of your dragon Pokemon. So if you had a Rayquaza with only 1 energy, attach the two to it, set down another rayquaza, rescue stretcher=rayquaza and 2 energy back to the bench, strong charge you're doing an additional 60 damage.
This is something I am gonna have to proxy up and test it out.
