Chaos Rising Pokémon Center Elite Trainer Box

Eleven packs rather than nine, with 65 card sleeves, basic Energy cards and dice alongside. Chaos Rising is small enough that the two extra packs are genuinely worth having: 86 cards in the main run and 122 in total means the pool is tight and each additional pack is a real increment. Set against that, Pokémon Center boxes are allocated rather than freely distributed in the UK, so they are scarcer than the standard edition and more likely to be marked up, and a large premium is hard to justify for two packs. Price it against a standard box plus a pair of loose packs. Mega Greninja ex is the card at the centre of the set, and Greninja consistently draws more attention than its rarity suggests.
