Pichu can help with setup, by attaching Lightning Energy with Crackly Toss.
Non-ex Raikou gives the deck an option against Pom-Pom Oricorio.

This deck has Pheromosa as an early-game attacker, being able to damage both Active Pokemon and Benched Pokemon. Once Decidueye ex is set up, it can attack the Pokemon that Pheromosa has damaged with Pierce the Pain.
The deck gains access to Hau, which can boost Decidueye ex's damage. Do note that this can only increase the damage of Razor Leaf, and Pierce the Pain if it is damaging the Active Pokemon.

Decidueye ex is a Stage 2 that benefits from Rare Candy, which greatly speeds up its setup, allowing it to immediately start attacking for only 2 Energy. Meowscarada is played alongside Decidueye ex, as a way for the deck to deal higher damage.
Decidueye ex can snipe any Pokemon on your opponent's side of the field if it has any damage, which makes it so no Pokemon is safe against Decidueye ex and Meowscarada's one-two combo!

Tsareena functions as the deck's primary attacker. It is able to attack quickly due to its efficient Attack Cost and can evolve into Stage 2 early with the Rare Candy.
Decidueye ex can work as a secondary attacker and finisher. If an opponent damaged by Tsareena retreats to the Bench, Decidueye ex can finish it off with Pierce the Pain.

Lurantis is a great partner for Decidueye ex because its Petal Blizzard Attack deals damage to each of your opponent's Pokemon for only one Energy. This Energy-efficient Attack synergizes with Decidueye ex's Pierce the Pain, making it so Decidueye ex can deal 100 damage to any Pokemon on your opponent's side of the field.
This ability to snipe allows the deck to cut cards like Cyrus and Sabrina, and make more space for Tool cards and HP recovery options like Erika and Lillie.
This deck makes use of Skill Dive Rowlet from Lunala Packs as Skill Dive lets you snipe any Pokemon for 10 damage, which synergizes with Decidueye ex's Pierce the Pain.

Greninja can support Decidueye ex's gameplan by providing Snipe support with Water Shuriken. Once both Pokemon are online, they are capable of dealing a total of 120 damage to any Pokemon on your opponent's side.
Both Stage 2s in the deck also benefit from Rare Candy which speeds up their setup.

![]() Guzma (A3 151) |
![]() ![]() • You can cut a copy of X Speed for a copy of Guzma to discard all of your opponent's equipped Pokemon Tools. This will remove additional health from Giant Cape or prevent you from taking damage from Rocky Helmet. |

Decidueye ex is able to naturally deal 80 with Razor Leaf to your opponent's Active Pokemon, allowing you to 2HKO most threats. But Decidueye's main attraction is its Pierce the Pain Attack, that can do 100 to any Pokemon on your opponent's side for two Colorless.
Decks with Decidueye ex can also afford to not run Cyrus because of its Ability to snipe for 100. This frees up more slots in the deck for other cards.




Decidueye ex and its partners may struggle to OHKO some Pokemon if healing cards put them out of KO range. Additionally, Pierce the Pain can only target Pokemon with damage on them. Immediately healing to full HP whenever you can will help your Pokemon avoid getting sniped.
HP Recovery and Healing Cards List



Use cards like Sabrina or Cyrus to gust out Rowlet and knock it out before it becomes a threat.
Hitmonlee is also capable of 2HKOing a benched Rowlet, forcing your opponents to evolve right away or risk losing it.

*update this with Lurantis, it synergizes much better with Decidueye since you can just attack all of their mons and then snipe the bench
