Game plan

Hit its Weakness. Mega Darkrai ex is weak to Grass, so those attacks do double damage. 22 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
Win the Prize trade. It gives up 3 Prize cards when Knocked Out. 10 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 3.
Plan for its big hit. Its strongest printed attack is Dusk Raid for 110+ (2 Energy). 707 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.
