Game plan

Hit its Weakness. Miraidon ex is weak to Fighting, so those attacks do double damage. 60 Standard cards can Knock it Out in one hit that way — the fastest needs just 1 Energy.
Win the Prize trade. It gives up 2 Prize cards when Knocked Out. 63 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 2.
Plan for its big hit. Its strongest printed attack is Cyber Drive for 220 (3 Energy). 159 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.
