Pre-launch preview. The format-side rules, plane catalog, and banlist are stable; per-card curation for multi-plane reprint sets (Modern Horizons, Mystery Booster, etc.) is still rolling in. Cards from those sets render as "pending" in the validator until curation lands.

Why this format

Plane Constructed is the format Magic was missing — flavor-anchored like Commander, competitively shaped like Standard, scoped by world instead of by era.

vs Standard

Themed metas, not power-creep races.

Standard chases the newest set. Plane Constructed locks the lens on a single plane's identity — Ravnica's guilds, Innistrad's tribes, Avishkar's artifice. Meta evolves through the plane, not against it.

vs Commander

Same flavor depth at 1v1 speed.

Commander's 100-card-multiplayer table is its own thing. Plane Constructed keeps the per-plane storytelling but compresses it to 60 cards × 1v1 — 50-minute matches you can grind.

vs Premodern

Curated by plane, not by era.

Premodern is an era cut. Plane Constructed is a flavor cut — every Ravnica printing across 20 years plays together, but Innistrad cards stay in their own format.

How it works

The 4-step loop. Familiar to anyone who's run a Standard event, with one twist: the plane is set by the event, not the player.

  1. 01

    Organizer picks a plane

    An event runs one plane: “Saturday: Ravnica Plane Constructed.”

  2. 02

    Players bring decks

    60-card decks where every card is canonically from that plane (basics universal).

  3. 03

    Standard 1v1 rules

    20 life, BO3 matches, 15-card sideboards (same-plane), 50-min rounds.

  4. 04

    Per-plane meta evolves

    Each plane is its own metagame. Win Innistrad — you're an Innistrad champion.

Crossing planes? Run Unified Plane Constructed instead — each player picks their own plane, pairings cross planes. Each player still picks one plane up front; only the pairing matrix differs.

Browse the planes

Every plane is a sub-format with its own meta, banlist, and signature cards. Tier signals card-pool depth — tier-1 has 1,000+ legal cards and is the launch focus.

Tier 1 — flagship planes

Tier 2 — substantial card pools, deeper exploration

Tier 3 & 4 — niche planes (18)

The 5 core rules

  1. 01
    Plane-anchored. A card is legal for plane X if it has at least one printing on a set canonically from plane X (including dual-tagged sets like NPH / ONE, which are legal in both Mirrodin and New Phyrexia).
  2. 02
    Basic lands are universal. Plains, Island, Swamp, Mountain, Forest, Wastes (and snow basics) are legal in every plane.
  3. 03
    Reprints inherit the set's tag. Plane-themed reprints (Innistrad Remastered, Ravnica Remastered, Mystical Archive on Arcavios) ARE legal on that plane. Reprints into multi-plane sets (Modern Horizons, Mystery Booster) aren't — those need per-card curation.
  4. 04
    Planeswalkers follow their home plane. Liliana Vess is always Dominaria. Chandra is always Avishkar. Vraska is always Ravnica. No matter what set they're printed in.
  5. 05
    Universes Beyond is its own plane. Doctor Who, LotR, Marvel, Final Fantasy, etc. Each UB franchise is its own plane-constructed format with its own meta and banlist — Doctor Who decks don't mix with Marvel.

Banned in every plane

These cards warp any plane they touch — Power Nine, fast mana, degenerate engines. Every plane's curator independently banned them at the format's founding. Individual planes layer their own meta-specific bans on top.

How it compares

Side-by-side with the formats players already know. Plane Constructed isn't trying to replace any of them — it sits in the open lane between Standard's rotation churn and Commander's table-game flavor.

Frequently asked

The honest answers to the questions players ask first.

Is this an official format?

No. Plane Constructed is a community-proposed format Mythic Decks built the canonical data for. It's not sanctioned by Wizards of the Coast. Stores and Discord communities can run events under it freely; nothing to license.

Where do I play?

Run local events at your store, or organize over webcam with friends. Mythic Decks doesn't host matches but provides the validator, banlist, and canonical set list to keep events on the same rules everywhere.

How do I find players?

Get into your local game store's Discord and propose a Saturday event. Post on r/EDH or r/magicTCG with the 'Plane Constructed' flag. At-the-table conversion is usually easy — most Commander players are curious about 1v1 plane formats.

Can I play Universes Beyond cards?

Yes — each UB franchise is its own plane-constructed format. Doctor Who Plane Constructed, Marvel Plane Constructed, LotR Plane Constructed, etc. A Doctor Who deck doesn't mix with Marvel; each IP plays as its own format with its own meta and banlist.

What about cards from Modern Horizons / Time Spiral / Commander products?

These are multi-plane sets — they introduce new cards from many planes at once. Per-card curation is in progress. For now, MH-only cards (Force of Negation, etc.) are pending: not legal in any plane until curated. The validator surfaces them as 'pending'.

Why can't I play Sol Ring?

Sol Ring is on every plane's banlist — it warps any plane it touches. The universal bans (Power Nine, Sol Ring, Necropotence, Mishra's Workshop, etc.) were applied as a baseline by every plane's curator. Individual planes can also ban plane-specific problem cards (Skullclamp on Mirrodin, Bridge from Below on Innistrad).

What if my favorite plane isn't tier-1 yet?

Every plane in the catalog is playable — tier just signals card-pool depth. Some tier-4 planes (Mercadia, Ulgrotha, Bablovia) have small pools but are very playable for casual or 'build with a constraint' events.

Can I run a draft or sealed variant?

Not in the current ruleset. Plane Constructed is constructed-only. A future variant — Plane Sealed (draft from one plane's set list) — is being discussed.

Is there a singleton variant?

No. Plane Constructed is 4-of like Standard. We considered a singleton parallel ruleset but decided against it — keeps the format definition clean and avoids splitting banlist maintenance. If you want singleton-flavored decks, build one yourself; the validator doesn't enforce the 4-of side either way.

What does 'canonical from a plane' mean for older cards?

A card is from plane X if it has at least one printing on a set tagged with plane X. We've curated all 714 Scryfall sets to canonical planes (or marked them multi-plane / unknown). The full breakdown is at /plane-constructed/sets.
