Season 4: Deck 2, 4 new Heroes, 4 new Factions, POW Leader

Season 4 launches with a new deck, 4 new factions, 4 new heroes and a new Leader. Multi-deck is here. Choose Deck #1 or Deck #2, each with its own heroes and factions — more strategic decisions, and a first for the auto-battler genre. Old decks never retire, so your favorite units are never vaulted. Invest in them forever! New Leader POW spawns an Experimental Box. Feed it any unit and the box takes on that unit's factions.
