See the main Sentinels Deckbuilding thread for the rules and intial two games. In general it's select up to four hero decks to build a single hero deck out of. It (and others) will then face a similarly constructed villain deck. Heroes are 2-0 so far, but villain constructers have also so far resisted the desire to build an unwinnable game as well.
Environment for this game will be one of these three: The Block, Time Cataclysm, or Realm of Discord. To selected at random at game start.
