How does it work?
Building decks
The two player from a team cannot share house, agenda and the banner cannot be from the house of the teammate.
So:
- Lannister fealty + Stark fealty <- no
- Lannister banner stark + Stark fealty <- no
- Lannister crossing + stark fealty <- yes!
Neutral cards (as you can guess) are not involved in this process.
(this part was edited)
The plot deck is one made of 14 plots. There can be only 1 plot which can be played twice in this expanded plot deck. At the start of the turn both players decide which plot to play from the pile.
The wars to come cannot be played.
(end of edit)
There are no further restriction.
Table talking
It's not forbidden, everyone can talk about whatever they wants, giving hints and advices. They can also share information about the cards they have in hand (eg "hey, don't worry I have an Handjudment if you fear Drakarys"). But it's forbidden to explicitly show a cards in hand. You can use this rule to your advantage and bluff.
Playing 2 vs 2
Seat are random but the two teams must play in a cross-like order (Player team A - Player team B - Player team A - Player team B ).
Most of the rules are shared with melee except the combat phase.
No titles are involved.
Plot phase
Important: each team can secretly* consult to chose which plot to play or not.
Marshalling phase
Starting from the first player each player can start to marshall stuff. Just like melee.
Combat phase
Each player can attack only people from the opponents' team.
A teammate cannot "support" his companion by declaring defenders on his/hers behalf.
Each player cannot receive more than one challange from each type.
And that's a limit that cannot be break by any card in play, so cards like that allow you to make more than one challange type are not really useful because even if the team could make, for example, a total of 3 military challange only 2 of them can be initiated, one against each opponent.
Dominace phase
The player with the highest "dominance value" wins dominance and score a point for his/hers house card, just like in melee. If there's a tie, even if only players from the same team are involved, it's still a tie and no one has won dominance.
Win condition
Once a team collect a sum 30 powers among their cards the team wins!
Once a player is out of the game due to decking condition the team is out aswell.
And that's it.
Feel free to give some feedbacks or advices!
Cheers.
*you can say that outloud if you are a moron, don't worry, I'm not judging.
