Game plan

Hit its Weakness. Eternatus is weak to Fighting, so those attacks do double damage. 86 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 World Ender for 230 (3 Energy). 142 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
Watch the Retreat Cost. It costs 2 Energy to retreat. If it gets stuck in the Active Spot, that's your chance.
