Pokemon TCG Pocket best Decidueye ex deck: Strategy and playstyle

Decidueye ex

• HP: 170
• Razor Leaf: Delivers a consistent 80 damage for two Grass Energy.
• Pierce the Pain: For two Colorless Energy, it targets any one of your opponent’s Pokemon that already has damage counters, dealing a solid 100 damage.

While Razor Leaf does straightforward decent damage, the real power of Decidueye ex lies in Pierce the Pain. This ability allows you to ignore the opponent’s active Pokemon and strike weak or damaged targets on the bench.

With its good bulk, Decidueye ex can stay on the field long enough to dish out repeated pressure and pick off important points.

Spiritomb

• HP: 80
• Swirling Disaster: Deals 10 damage to every opposing Pokemon.

Even though its damage can appear disappointing on initial glance, Spiritomb takes on a key support/setup role. Its spread damage puts pressure on the other Pokemon, opening up crucial chances for Decidueye's Pierce the Pain.

It also provides you with room to maneuver and position your bench without being strictly passive, quietly altering the board state in your direction.

• Rare Candy: This is crucial to speed up Rowlet’s evolution into Decidueye ex in a single turn, skipping the middle stage entirely.
• Leaf Cape: Boosts Decidueye ex’s HP by 30, turning it into an even bulkier threat that’s harder to knock out.
• Poison Barb: Best used on Spiritomb, it punishes opposing attackers with Poison, adding chip damage and encouraging misplays or switching.
• X Speed: Grants a free switch between benched and active Pokemon, a strong tempo tool when repositioning attackers or stalling.
• Iono: A solid hand reset tool.
• Poke Ball: Helps you find and play basic Pokemon early, aiding consistency.
• Professor’s Research: Draws 2 cards; refreshes hand.
• Lillie: Heals 60 HP from a Stage 2 Pokemon, perfect for sustaining Decidueye ex in prolonged battles.

Pokemon TCG Pocket best Decidueye ex deck: Alternative options to consider

If you’re looking to customize or adapt the deck, consider these substitutions:

1. Lurantis: Its Petal Blizzard deals 20 damage to all opponent Pokemon for just one Grass Energy. It’s more potent than Spiritomb in terms of damage output, but requires evolution from Fomantis.
2. Greninja: With Water Shuriken, it deals 20 damage to any opponent’s Pokemon. A great way to activate Decidueye’s Pierce the Pain, though it may require Grass- and Water-type energy management.
3. Erika: Cures any Grass-type Pokemon for 50 HP. Although Lillie restores more, Erika is not bound to Stage 2 Pokemon, so she's more versatile, particularly if you count other Grass evolutions such as Lurantis.

The Decidueye ex deck provides a combination of systematic targeting and consistent frontline presence, backed by effective healing, evolution acceleration, and status effects, so when selecting alternate cards, bear that in mind
