Strengths

  • 180 HP is one of the highest base HP values for a Stage 2 ex, and Sparkling Aria adds 20 healing each use, making Primarina ex extremely hard to knock out in two turns.
  • Hydro Pump scales with energy load; attaching extra water energy naturally each turn ramps the damage ceiling without special conditions.
  • Favorable into Houndstone (75%), Silvally (75%), and Mega Heracross ex (69%); excels against decks that lack efficient water-type counters.

Weaknesses

  • Primarina ex is an ex: a knockout gives the opponent 2 points, so all the HP investment is lost the moment it falls.ex KO
  • Stage 2 setup through Popplio requires two evolutions or Rare Candy; slow opening hands hand the opponent free early turns.Consistency
  • Melmetal ex (25%), Gholdengo ex (25%), and Meowscarada ex (25%) matchups show that electric-type and high-burst opponents shut it down before it heals.Matchup

Strategy Guide

Auto-generated

Primarina ex (180 HP) wins by leveraging Hydro Pump's scalable damage — 40 base plus 40 more with an extra water energy attached — and Sparkling Aria's 100 damage with 20 self-healing to become one of the most resilient Stage 2 ex attackers in the game. The deck pairs Primarina ex with Darkrai and Igglybuff to fill the bench while the water line sets up.

Open by finding Popplio with Poké Ball and benching Darkrai and Igglybuff alongside it. Use Professor's Research, Copycat, and Rare Candy to evolve Popplio toward Primarina ex. Memory Light supports evolution line continuity. Once Primarina ex is active with two or more water energy, Hydro Pump deals 80 when a second water is attached; three water energy unlocks Sparkling Aria for 100 plus 20 healing. Leaf and Cyrus help manage the opponent's board while you build.

Full-power mode; net effective HP restoration extends Primarina ex's survivability

How to Play

Ramp Water Energy for Hydro Pump Damage and Sparkling Aria

Attach water energy to Primarina ex every turn. With two energy Hydro Pump hits 80; with three, Sparkling Aria deals 100 and heals 20. The healing compounds over multiple turns, effectively raising Primarina ex's HP ceiling well beyond 180. Sabrina can pull a damaged Pokemon off the bench if needed.

Use Darkrai and Igglybuff for Early Non-Ex Bench Presence

Darkrai and Igglybuff fill out the bench without handing the opponent 2 points on knockout. Leaf and Cyrus supplement the trainer suite to manage the opponent's board while Primarina ex charges. Memory Light assists with the evolution chain when natural draw is slow.

How to Beat This Deck

Use Electric-Type Attacks to Exploit Water Weakness

Melmetal ex at 25% favorable win rate for Primarina ex indicates electric and metal type attacks are highly effective. Electric attackers with 70+ base damage exploit water weakness to one-shot or pressure Primarina ex before it accumulates the three energy needed for Sparkling Aria's healing to matter.

Deny Rare Candy and the Second Evolution

Primarina ex needs either two natural evolution steps or Rare Candy to reach Stage 2. Disrupting hand quality with Mars-style discard effects or bench-sniping Popplio before it can evolve collapses the deck's only real win condition. A knocked-out Popplio scores only 1 point but removes the entire attacker pipeline.

Pressure With High-Burst Two-Turn Knockouts to Race the Healing

Sparkling Aria heals 20 per turn. An attacker that deals 80 or more per turn on 180 HP forces a two-turn knockout even accounting for healing. Stack chip damage with bench-splash attacks on turn one, then finish Primarina ex with a full attack next turn before it can use Sparkling Aria a second time.

Common Substitutions

Early non-ex bench support

  • Darkrai:2x in top build; fills the bench as a non-ex so the opponent scores only 1 point on knockout.
  • Igglybuff:2x in top build; bench utility that fills out the early board without contributing to the opponent's point total.
