Carte Magic Charred Foyer // Warped Space

Charred Foyer // Warped Space is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

At the beginning of your upkeep, exile the top card of your library. You may play it this turn. (You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.) Once each turn, you may pay {0} rather than pay the mana cost for a spell you cast from exile. (You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.)

Complete guide

Charred Foyer // Warped Space is a versatile Room enchantment that provides consistent card advantage and late-game mana acceleration. By unlocking its doors, you can bridge the gap between early resource management and casting massive spells for free. This red enchantment is perfect for decks that want to utilize exile as an extended hand.

Unlocking the Room

Charred Foyer // Warped Space functions as a Room permanent. When you cast it, you choose one side to unlock; you only pay the mana cost for that specific half. Once it is on the battlefield, the other door remains locked until you pay its mana cost as a sorcery. Charred Foyer provides a triggered ability at the start of your upkeep, while Warped Space offers a powerful static ability that lets you bypass mana costs.

Step-by-Step Resolution

During your upkeep, if Charred Foyer is unlocked, its ability triggers, exiling the top card of your library. You gain permission to play that card until the end of the turn, following all normal timing rules (e.g., lands during your main phase). If Warped Space is also unlocked, you may choose one spell you cast from exile each turn and pay {0} instead of its mana cost. Note that you still pay mandatory additional costs, but you cannot use other alternative costs like 'Overload' when choosing to pay {0}.

Common Pitfalls

A common mistake is forgetting that playing a card via Charred Foyer still follows timing restrictions. You cannot play a land card exiled this way if it is not your turn or if you have already used your land drop. Additionally, if a spell has {X} in its cost and you use Warped Space to cast it for {0}, X must be 0.

Strategic Implementation

This card is most effective in decks that generate additional value from exile or have high mana-value finishers. By using Charred Foyer to find your threats and Warped Space to cast them for free, you can maintain tempo while saving your mana for other responses or for unlocking additional Rooms.

Interaction examples

Flipping a High-Value Saga

During your upkeep, the Charred Foyer door triggers and exiles Summon: Bahamut. If the Warped Space door is also unlocked, you can choose to cast Summon: Bahamut for {0} mana. Because this is a spell cast from exile, it qualifies for the free cost once during your turn.

Navigating Multiple Rooms

If you use Charred Foyer to exile Ticket Booth // Tunnel of Hate, you may cast either half of that Room card from exile. If Warped Space is unlocked, you can pay {0} to cast either Ticket Booth or Tunnel of Hate. Once cast, the chosen door enters the battlefield unlocked as normal.
