Magic: The Gathering

MTG has the deepest catalog of any game on Sideboard — thousands of sets spanning decades, multiple parallel product lines (main sets, Commander, Secret Lairs, Universes Beyond, Art Series, promos), and more variant types per card than any other game. The complexity is handled behind the scenes; what you see is a clean catalog with accurate per-variant pricing.

Sets & Catalog

Sideboard maintains a complete catalog of every TCGPlayer-listed MTG set, including:

• Standard and modern sets — Bloomburrow, Duskmourn, Foundations, and all current sets
• Commander products — preconstructed decks and Commander-specific sets
• Secret Lairs — tracked as their own product type; each drop appears as a distinct set
• Universes Beyond — crossover sets (Lord of the Rings, Assassin’s Creed, Final Fantasy, Fallout, etc.) are cataloged separately, not merged into their thematic era
• Promo packs and prerelease promos — tracked as supplemental sets linked to their parent expansion
• Art Series — cataloged as separate products
• Older sets — the catalog includes sets back to Alpha, though some foreign-market-only prints (Renaissance Italian, Salvat Spanish) are not on TCGPlayer and won’t appear

New sets typically appear in Sideboard’s catalog within 24 hours of TCGPlayer listing them.

One thing to know: Because MTG has so many set variants, not every regional or limited print is covered. MTGO-only sets and some niche promo subsets from TCGPlayer’s back catalog are excluded.

Cards & Variants

MTG has the richest variant library of any game on Sideboard. Each unique product on TCGPlayer is tracked as a distinct entry, so a card with a regular print, a borderless version, a foil etched version, and a Japanese alternate art all appear as four separate items in your catalog. This means:

• Showcase and borderless treatments are distinct catalog entries
• Japanese alternate art versions (e.g. Strixhaven Mystical Archive Japanese variants) appear alongside the English prints — importing a set like Strixhaven bumps the product count from ~63 English cards to over 250 when Japanese alternates are included
• Collector Booster exclusives (etched foil, extended art) are tracked separately
• Prerelease stamped cards appear as their own entries

Finishes

Sideboard tracks three finishes for MTG:

These are separate price rows — a Near Mint Foil and a Near Mint Normal of the same card have independent prices. When building buylist rules, you can target any combination of finish and condition.

Card metadata

Sideboard enriches MTG cards with detailed card metadata:

• Oracle text, mana cost, colors, color identity
• Type line and subtypes
• Format legality (Standard, Pioneer, Modern, Legacy, Commander)
• Power/toughness for creatures, loyalty for planeswalkers

This enrichment is available for filtering in the catalog and in buylist rules — you can write rules that target only red cards, only instants, or only cards legal in Pioneer.

Pricing

MTG pricing from Sideboard covers all variant/finish combinations that have real market data:

• Cards in your active inventory refresh prices every 6 hours
• Cards you don’t stock refresh daily
• Prices are tracked per condition (Near Mint through Damaged) and per finish (Normal / Foil / Etched Foil)

See How pricing works for full details on how Sideboard syncs and displays prices.

Note: Very new cards in a just-released set may have limited pricing data for the first day or two after launch, as the market develops. Pricing activates automatically once market data is available.

Common Workflows

Managing a new set release:

1. The set appears in your catalog automatically within 24 hours of TCGPlayer listing it
2. Pricing populates on the next pricing run after the catalog refresh
3. Add singles to inventory via the Catalogue page — search by set name, then add quantities per card and condition

Handling Secret Lairs:

• Each Secret Lair drop is its own set entry, separate from the base set of any reprinted cards
• If you stock a card that exists in both a Secret Lair and a regular set, they appear as separate items with separate prices and inventory counts

Filtering by format in buylists:

• Use the Format legality filter when building buylist rules to buy only cards legal in specific formats (e.g., “buy all Pioneer-legal cards above $5 at 50% market”)

Gotchas

Universes Beyond ≠ the crossover theme. Lord of the Rings cards are in the “Universes Beyond” product type, separate from the main set calendar. If you’re filtering by product type to find “all recent expansion sets,” UB sets won’t appear unless you explicitly include them.

Secret Lair reprints are separate from the original printings. A Thoughtseize from a Secret Lair is a different catalog item than one from Theros or Modern Masters. Prices, inventory, and buylist quantities are tracked independently.

Foreign-market prints. A small number of sets (Renaissance Italian/German, Salvat Spanish encyclopedia, some Chinese tournament exclusives) aren’t on TCGPlayer and don’t appear in Sideboard’s catalog.

“Which etched foil is this?” When multiple Collector Booster versions of the same card exist (foil extended art, etched foil, regular extended art), they’re separate catalog entries with different TCGPlayer IDs. The card name in Sideboard includes the treatment description to tell them apart.
