Collection

Deckbuilding and loadouts

Implemented local

Deck & Trunk saves 12–40 card loadouts containing creatures, standalone spells, Scheme traps and prepared attachments.

Watch the Trunk in action

Build your first two decks

Follow a real in-game Trunk walkthrough with Flint: drag cards into a fresh 12-card deck, add compatible enchantments, save it, build and save a 40-card deck, then reopen and edit the earlier build. The guide explains card roles, synergies, signature limits and Scheme traps.

Use the player’s CC control for English captions. On a phone, rotate to landscape and use fullscreen to read card details.

This guide uses a capture-only collection with every designed card visible so you can compare options. Your own Trunk shows the copies you have earned.

Step by step

How it works

  1. Choose a champion, then add 12–40 owned cards with at least eight creatures.
  2. Keep no more than twelve standalone spells or traps, including no more than three Scheme traps, and obey every card's printed copy limit.
  3. Attach magic only to open creatures. The total attachment limit is max(4, one slot per five cards rounded up): four at 12 cards and eight at 40; most attachment designs allow two copies and named exceptions allow one.
  4. Keep Open the Well and A Letter from the Well to two combined, then resolve every ownership or legality warning before saving.

Rules this mechanic controls

  • Keep at least eight creatures, at most twelve non-creatures and at most three Scheme traps.
  • Each card uses its printed copy limit; most designs allow two, while named exceptions and signature cards allow one.
  • Prepared attachments scale with deck size: four slots at 12 cards and one additional slot per five cards, up to eight at 40; an attachment design normally has a two-copy limit and named exceptions have one.
  • Editing validates ownership, open or sealed hosts, combined Well-return limits, duplicate limits and active-match locks.

Worked example

A 12-card deck may contain two copies of an ordinary open creature and four prepared attachments total. A 25-card deck may prepare five attachments. A one-copy signature card or attachment remains limited to one even when the deck has unused slots.
