How to beat Reuniclus

Reuniclus has 2 versions in the 2026–27 Standard format, with up to 140 HP as a Psychic Pokémon. Here's the maths for Knocking it Out — worked out from every Standard-legal card.

Game plan

1. Hit its Weakness. Reuniclus is weak to Darkness, so those attacks do double damage. 75 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
2. Don't over-invest. It only gives up 1 Prize card, so avoid spending a big two-Prize attacker on it if a cheaper Pokémon can do the job.
3. Avoid Fighting attacks. Reuniclus resists them, so they do less damage.
4. Plan for its big hit. Its strongest printed attack is Brain Shake for 100 (2 Energy). 835 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
5. Watch the Retreat Cost. It costs 1 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.

One-hit Knock Outs using Weakness

These Darkness attacks do at least 140 after Weakness. Fastest (fewest Energy) first.

One-hit Knock Outs without Weakness

Attacks with a printed 140+ damage (after Resistance).

Pokémon that survive its biggest attack

These can take a printed 100 from Brain Shake and stay in play (Weakness included). Single-Prize Pokémon first.

Every Standard Reuniclus card

Damage is the number printed on the card. Attacks marked + or × can do more, and Abilities, Tools and Stadiums can change the maths — always read the card. Energy letters: G Grass, R Fire, W Water, L Lightning, P Psychic, F Fighting, D Darkness, M Metal, N Dragon, C Colorless (any Energy).
