avatar the last airbender collector booster box msrp Magic: Gathering The Box, 12 Packs including 5 cards of rarity Rare or higher and 4 Uncommon Wizards of The Coast Magic:

Available in both Foil / Non-Foil finishing

This set established the TCGs rules language and card layout, so almost every later set is based on what the Base Set introduced

(2025-06-06) If two or more effects attempt to modify how many counters would be put onto a creature you control, you choose the order to apply those effects, no matter who controls the sources of those effects

SPECIAL BONUS: Each Decks 51st card is a fully-playable chibi art version of that Signers main monster (for Yuseis Deck, thats a chibi Stardust Dragon)
