How to build and share a Monster Train 2 deck

  1. Choose the primary and allied clan. The card pool includes those clans plus neutral cards. Leaving both unselected lets you explore the full database.
  2. Search card names and add your picks. Click a card to add one copy; use the plus and minus controls in your deck to adjust quantities. “Show next” reveals more of the pool, and searching always checks every matching card.
  3. Read the Ember curve and composition. Counts include each copy of a card. X-cost cards keep their own category, and cards without a fixed playable cost are shown separately. Shared keyword and subtype labels help you identify connections to investigate.
  4. Save or share the list. “Save deck” keeps a named copy in this browser. “Copy share link” stores the active clans and card quantities in a URL that opens on another device. “Export text” copies the card list and that link.

Does this calculate damage or enforce in-game deck rules?

This is a manual planning tool. It does not simulate combat, apply upgrades, relics, Pyre Hearts or Souls, or enforce a champion limit. Changing clans filters the available pool but keeps cards already in your deck so you can compare plans without losing your list. Review those cards before treating the list as a run plan.

Where are my saved decks?

Saved collections belong to this browser and device; there is no account or cloud sync. A share link reopens the active card list but does not include its saved name or your other decks. Keep share links before clearing browser data. The storage and sharing policy explains what a URL exposes.

What should I draft next?

Open a card's name in your deck to inspect its exact effect, compare available upgrades, and check the clan-by-clan draft priorities. For an opening plan, start with champion upgrade paths; after the run, record the result in the Run Tracker.
