## Official Rulings
- *(2020-11-10)* Spells that target more than one commander you control cost only {3} more to cast.
- *(2020-11-10)* To determine the total cost of an opponent's spell that targets a commander you control, start with the mana cost or alternative cost that player is paying, add any cost increases (such as that of Esior's middle ability), then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
- *(2020-11-10)* If something refers to your commander while you have two commanders, it refers to one of them of your choice. If you are instructed to perform an action on your commander (e.g. put it from the command zone into your hand due to Command Beacon), you choose one of your commanders at the time the effect happens.
- *(2020-11-10)* To have two commanders, both must have the partner ability as the game begins. Losing the ability during the game doesn't cause either to cease to be your commander.
- *(2020-11-10)* Both commanders start in the command zone, and the remaining 98 cards (or 58 cards in a Commander Draft game) of your deck are shuffled to become your library.
- *(2020-11-10)* An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
