In the past I had made a deck called AWESOME Energy discard. It was a good concept and even got deck of the day, but because rotation happens tomorrow, I wanted to make a post rotation version of the same deck.
The goal is to use Destructive Finish on Radiant Steelix as your first attack, once you have Bibarel in play. Caitlin will help make sure you do the max amount of damage. Then use switch or switch cart to switch Steelix out and use Hisuian Basculegion's upstream spirits for a whole lot of damage, also replinishing your deck. Once you do that your deck will be purely energy, so Kyogre's Aqua storm can finish off doing 250 damage to 2 of your opponent's pokemon.
