DECKBUILDING
SETTING UP: Before play, create two decks. One consists of 10 level 0 Coin cards that read “(Coin) Gain 1 Coin”, two of which may have either the passive ability “When discarded, draw a card” or “When discarded, make another player discard a random card”. The second deck consists of all the rest of your cards, called the Stock.
PLAY: At the start of each turn, flip over four cards at the top of your Stock and shuffle any previously revealed Stock cards back into it. You may pay Coin equal to a card’s level to add it to your hand. Coin is retained between turns. Cards don’t require sacrifices to be played. At the end of your turn, draw back up to 5 cards. If your deck is empty, shuffle your discard pile back into it. Whoever reaches the Act Threshold first wins.
You probably want to make custom cards for this play mode that deal with drawing more cards, discarding cards, interacting with Stock and gaining Coin. Most decks should still work for this mode though, just might struggle to get cards on the board without having ways to get more Coin.
