The deck's central idea is simple: load as much Basic Energy as possible across your Pokémon, then discard it all in one go with Raging Bolt ex's Bellowing Thunder, which does 70 damage for each Basic Energy you discard from your Pokémon. With four copies of Crispin in the list, each turn you can search your deck for up to two Basic Energy cards of different types, put one into your hand and attach the other directly to one of your Pokémon. That alone puts two Energy into play every turn you play a Supporter.

Teal Mask Ogerpon ex speeds that process up further. Its Teal Dance ability lets you attach a Basic Grass Energy from your hand to it once per turn, and if you do, you draw a card. With three copies in the list and seven Basic Grass Energy available, you can chain Teal Dance with Crispin to build a large Energy board while keeping your hand stocked. Latias ex's Skyliner ability then removes Retreat Cost from all your Basic Pokémon, so you can swap freely between attackers without burning Energy Switch.

Energy Switch - four copies here - moves a Basic Energy from one of your Pokémon to another, letting you concentrate energy onto Raging Bolt ex right before it attacks. Iron Leaves ex adds another way to redirect Energy mid-turn: when you play it from your hand onto the Bench, Rapid Vernier lets you switch it into the Active Spot and move any amount of Energy from your other Pokémon onto it, then fire off Prism Edge for 180 damage. Mega Kangaskhan ex sits at 300 HP and provides a draw engine on any turn it spends in the Active Spot, with Run Errand drawing 2 cards once per turn.

Meowth ex's Last-Ditch Catch ability fetches any Supporter from your deck when it comes down from your hand, guaranteeing access to Crispin or Boss's Orders whenever you need it. Fezandipiti ex covers the turns after you lose a Pokémon, drawing 3 cards via Flip the Script if any of your Pokémon were knocked out last turn. Area Zero Underdepths extends your Bench to eight Pokémon while you have Tera Pokémon in play, giving you room to keep all your energy-bearing Basics on the field at once.
