The "deck" is the collection of words that is built at the start of each session. Each player should submit 5-10 words to the Storyteller, who will aggregate and approve. This document assumes that words are submitted on individual index cards and then shuffled.
If you submit a word that's a homonym, such as "lead", be sure to specify which one you mean. Players (and enemy fate weavers) will draw from the deck any time they fully succeed at a skill check or land the killing blow on an enemy. When the deck is emptied, take a moment to have everyone generate additional words.
