Timeways mechanics: Rewind and Fabled
Fabled cards add companions to your deck. Rewind lets you keep a random result or try it again.
Fabled
Adds two special companion cards to your starting deck. The Fabled card and its two companions use three normal deck slots.
Fabled+
Adds nine special companions to your starting deck. This is a separate keyword. It is not an upgrade that every Fabled card can earn. Rafaam and his nine companions use ten slots in his 40-card deck.
Rewind
After you see a random result, keep it or undo it and try again. The new result may be different.
Count the full package
Companions take normal deck slots. Judge them along with the main Fabled card when building a deck.
For Rewind, compare the result you have with the results you might get. A useful result may be better than risking a bad one to chase the best one. Pick for your board and plan, not just because the first result felt dull.
