What's in a Mega Symphonia box
Each box holds 30 packs of 5 cards, so 150 cards. A sealed box with intact factory film is the easiest way to know it hasn't been searched. See how to spot a fake or resealed box.
Nothing in a Japanese box is officially guaranteed, but sealed boxes follow a strong pattern. See below.

What's guaranteed in a box
Sealed Japanese boxes follow a strong pattern: 1 Super Rare or better, 1 Item, Tool or Stadium Super Rare, 3 Art Rares and 4 or 5 Double Rares. It applies to factory-sealed full boxes only. Loose packs and resealed boxes don't follow it, and it isn't an official promise: The Pokémon Company prints only the box setup and that cards are inserted randomly. The pattern doesn't say which hit you get. English Mega Evolution boxes have no box guarantee. Every English pack is random.

Mega Latias ex 088/063 and Mega Kangaskhan ex 089/063 are the other Mega Special Art Rares, and Acerola's Mischief 090/063 leads the Supporters. Mega Symphonia's twin set, Mega Brave (M1L), came out the same day with Mega Lucario ex. Prices move daily, and none of this is a promise of what you'll pull.
