Win the Prize trade. It gives up 3 Prize cards when Knocked Out. 15 single-Prize Pokémon can take it out in one attack, so you trade 1 Prize for 3.
Avoid Grass attacks. Mega Mawile ex resists them, so they do less damage.
Plan for its big hit. Its strongest printed attack is Huge Bite for 260 (3 Energy). 98 Standard cards have enough HP to survive one hit — before any Weakness, + or × effects.
