a dominion-style experience for 2-4 players
‣ 10 cards from the cube are laid out faceup to form the market
‣ players start with 30 life
‣ starting hand size is 0 cards
‣ each player receives a 12-card starting deck:
triggers
‣ at the beginning of the draw step on your turn, draw 5 cards (first player instead draws 3 cards on the first turn)
‣ if you'd draw a card while your library is empty, instead shuffle your graveyard into your library then draw a card
‣ at the beginning of the end step preceding your turn, discard your hand
actions
‣ you may not play lands; instead, you may discard a land at any time to activate one of its tap abilities (instant speed)
‣ as a special action once per turn you may play a card from your hand without paying its mana cost (you may play other cards by paying their mana cost as usual)
‣ as a special action as often as you like you may buy a card from the market by paying its generic mana value (or 
for a land), put it in your graveyard, then replace it
‣ as a special action as often as you like you may pay to exile all cards from the market then replace them
reminders
‣ special actions may only be taken on your turn as a sorcery
‣ when playing a card without paying its mana cost, you can't pay alternative costs, and x is 0. you may pay additional costs, and must pay them if they're mandatory
‣ looking at or putting from the top of your library aren't draw effects that trigger a shuffle up
playing on cockatrice is easy, but will require manual actions by one player to manage the market
download the 12-card starting deck and use that (or make their own with 2 of each of chromatic star and the 5 basic lands) and load into the game as usual
create a second rooster rangers account, so you can play on one and manage the market on the other (this is easier if you have a second monitor for the shop account, but not required)
to get the cube list, simply export the cubecobra list as a .txt, copy the mainboard cards to your clipboard, load the deck editor in cockatrice, ctrl+shift+v, paste in, and save deck
launch cockatrice.exe twice, log in to your two accounts, and create a game as usual, but with the player starting health at 30. once in, on the market account, simply drag ten cards from the deck into the host's 'the stack' zone to create the market, then roll for starting player as usual
managing the market
‣ when a player purchases a card, drag that card from the stack onto that player's land zone and replace it. they can then move the purchased card into their own graveyard
‣ when refreshing the market, lclick+dragabox around the old cards, move to exile, then replace
