Start with the official lists

The gallery covers new cards and special treatments. The product overview contains the full Planeswalker-stamp reprint list; the gallery alone is not the entire 2,000-plus-card pool.

Card categories & the full draft pool

Categories identified in official MBC sources
CategoryCount or identifierWhat to know
New / digital-to-paper cards60; collector numbers 1–6059 new cards plus one previously digital-only card. Their format legality begins on the dates in the current product overview.
Acorn-stamped Alchemy cards10; collector numbers 61–70Not Constructed-legal. Playable in MBC Draft and Sealed.
Playtest cards121The selection returns from Mystery Booster 2. These are for MBC Limited, not normal Constructed play.
Future Sight frame cards134A special frame treatment. The frame is not an independent grant of format legality.
Planeswalker-stamp reprintsSee official reprint listA wide selection from Magic’s history, retaining their existing format legality.

These categories describe contents and treatments. Do not add them together to claim a count of entirely new cards; MBC contains many reprints.

Three cards that help explain the rules

Seluma, Light of Aysen

Read Seluma’s deckbuilding example →

A Rulebreaker example: a deck with Seluma as commander can include Angel cards of any color identity and any basic lands. The exception does not erase other deckbuilding restrictions.

Tolabow, Loch Rascal

Compare Tolabow’s color choices →

Use the corrected Oracle text, not an ambiguous reading of the printed text. The extra-color permission for instants and sorceries explicitly refers to color identity. Read the official correction.

Tsagan, Raider Warlord

The product overview identifies Tsagan as the digital-to-paper card without an acorn stamp. Its status differs from the ten acorn-stamped Alchemy cards.

What’s in a booster?

Each box contains 24 boosters; each booster contains 20 cards. The official product overview gives the color slots, reprint commander, new commander, special treatment slot, and playtest card slot. Pull rates and slots should be checked there rather than inferred from the gallery.
