To unlock Abbey access in Card Monarchy, open the Forge, make sure your active deck contains exactly 10 cards with no duplicate card, then click Done or Back and select the Abbey from the Monarchy Hub.

Build a complete deck in the Forge

  1. From the Monarchy Hub, select the Forge.
  2. Choose a suit tab in the Collection on the left: Hearts, Clubs, Diamonds, or Spades.
  3. Double-click cards in the Collection to add them to the open decklist.
  4. Check the decklist count. It must show 10/10.

Card countExactly 10 cards
DuplicatesNo more than 1 copy of any card

To remove a card, double-click its entry in the decklist. Hover over an entry to view the full card.

Select the deck that Abbey will use

  1. Click a decklist to open it.
  2. Confirm that it contains 10/10 cards.
  3. Make sure it is marked Active. If you maintain multiple decklists, only the active one is used for your next run.
  4. Click Done or Back to return to the Monarchy Hub.

Enter the Abbey

  1. Click the Abbey on the Monarchy Hub.
  2. A new run begins and the Abbey map opens.

The Abbey remains greyed out if any required decklist is incomplete. Hover over the Abbey to see which decklist is short and how many cards it needs.

Manage decklists

  • Use + New Decklist to create another named decklist. A save can hold up to 8 decklists.
  • Use Rename to change the open decklist's name.
  • Use Copy to duplicate the open decklist and make a variation.
  • Use Delete to remove the open decklist after confirming.

If the Forge is locked

Your deck cannot be changed while a run is in progress. Finish or abandon the current run first; then return to the Forge and edit the deck.

If selecting the Abbey returns you to an existing run instead of opening deck building, that run is still active and the Forge remains locked until the run ends.
