Game plan
- Hit its Weakness. Tapu Koko is weak to Fighting, so those attacks do double damage. 108 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
- 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.
- Plan for its big hit. Its strongest printed attack is Thunder Blast for 130 (3 Energy). 399 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
- Watch the Retreat Cost. It costs 1 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.
