The cover star is Mega Rayquaza ex, one of the most wanted Pokémon in the hobby. We expect its top-rarity versions to be the main chase card of the set. It's joined by three more new Megas:

With 14 Illustration Rares in the set, there's plenty for art collectors too.

New Mechanic: Legendary Split Stadium Cards

One of the most interesting changes in Delta Reign is the return of split cards. The new "Legendary" Stadium cards come in two halves, a lot like the LEGEND cards from the HeartGold & SoulSilver era. Players can only include two sets per deck, so expect deck builders to test them hard.
