Decidueye EX and Vivillon with Dudunsparce draw engine

This deck centers around setting up Decidueye ex as your main attacker while using a strong engine built around Dudunsparce and Vivillon.

The ideal setup starts by getting Rowlet on the board early and evolving into Decidueye ex as quickly as possible. At the same time, you want to establish your *****erbug → Spewpa → Vivillon line. Vivillon plays a key role by disrupting your opponent’s hand while also helping set up Decidueye ex’s ability, giving you both control and synergy rather than raw draw

This deck centers around setting up Decidueye ex as your main attacker while using a strong engine built around Dudunsparce and Vivillon.

The ideal setup starts by getting Rowlet on the board early and evolving into Decidueye ex as quickly as possible. At the same time, you want to establish your *****erbug → Spewpa → Vivillon line. Vivillon plays a key role by disrupting your opponent’s hand while also helping set up Decidueye ex’s ability, giving you both control and synergy rather than raw draw power.

The main draw engine comes from Dunsparce. By attaching Enriching Energy, evolving into Dudunsparce, and using its effect, you can consistently refill your hand. This loop can be repeated or recycled to maintain strong momentum throughout the game.

Decidueye ex acts as your primary damage dealer, benefiting from the steady setup and disruption. Supporting Pokémon like Fezandipiti ex and Meowth ex provide additional utility and flexibility depending on the matchup, while Relicanth enables an additional layer of strategy.

With Relicanth in play, you can take advantage of your evolution lines’ attacks in combination with Vivillon and tools like Ignition Energy to snipe key pieces on your opponent’s bench. This gives the deck a strong disruption angle, allowing you to pick off support Pokémon and interfere with your opponent’s setup while you continue building your board.

Your Trainer lineup focuses on consistency and recovery. Cards like Ultra Ball and Buddy-Buddy Poffin help you find your pieces early, while Night Stretcher and Poké Pad allow you to recover key resources and extend your plays into the late game. Boss’s Orders gives you control over your opponent’s board to pick off key threats.

Overall, this is a setup-heavy deck that rewards smart sequencing. Once established, it maintains strong hand advantage through Dudunsparce, applies pressure with Decidueye ex, and disrupts opponents with Vivillon while threatening the bench with targeted knockouts.
