white dragon pokemon card Latios (10/20) [Black & White: Vault] [Fairy]2 Dragonair - SWSH12: Silver Tempest

Build your sealed deck with six Draft Boosters and two foil-stamped promo cards: a rare or mythic rare from the set plus a beautiful borderless scene card to assemble a scene available only through Prerelease Packs and Collector Boosters

The M-EX variant simply means Mega EX

its treated as a special action. Special actions are things you can do that dont use the stack

I tried to keep them relatively simple (as simple as madness can be for newer players), but if you have ideas to let them intersect multiple archetypes in the cube that would be even better

In this deck, however, its another artifact creature that also just happens to make both sides of Tetzin doubly good
