I will quote you a part of the EDHLR rules that are for remaking games:
* You may remake/leave a game if game status is other than 5v5, 5v4 or 4v4
* You may remake/leave a game if game status is other than 5v5 and the team scores are 0-0 and game has lasted no longer than 7 minutes.
* Users who have been afk/idle for a total of 5 minutes or more count as leavers when determining game status.
* You are not allowed to forfeit.
* At any time during a game you can vote to remake/cancel a game. In order to remake/leave the game, the majority of all players must agree, including those in the opposite team.
* Only users who confirm that they wish to remake/cancel the game count. Users who do not reply count as having voted to play on.
* If you remake/leave a game after a voting, you MUST save the replay in order to be able to prove that the majority of all players agreed, otherwise you will get banned if someone reports you!
* The host of a game has no special rights to decide when to remake/cancel a game. Hosts remaking a game without fullfilling the criteria stated above will be counted as LEAVERS!
