Commander Legends releases on November 20, 2020. They do not apply to your sideboard.
We all know that. Brew with restrictions!
RIP Flash | The Command Zone | Magic: The Gathering Commander / EDHThe Command Zone – MTGnews-O-Rama, RC Statement on secret lair: the walking dead, Gavin’s Format of the Month – August 2020: Sideboards.
Previously, the active player chose relative timestamps for all the things. Taking responsibility for your and your opponents’ fun, including setting expectations with your group, is a fundamental part of the Commander philosophy. If another card comes along that also does something novel that is incompatible with the format, we’ll ban it immediately. It should not be taken as a signal that we are considering any kind of change in how we intend to manage the format; this is an extraordinary step, and one we are unlikely to repeat. Your companion begins the game outside the game. Time will tell.
That left Lutri.
Mutate aside, this has always been true, and it's finally clear and explicit in the layers section of the rules. Once a player has chosen not to reveal a companion, that player can't change their mind.
The companion ability lists a deckbuilding rule. Those counters actually went poof, but this rule covers the gap to let us use words that encourage you to use that same pile of beads or dice or coins or kittens to represent them.
Announcement Date: June 1, 2020. All we had to do was change one word in Rule 11: 11: Abilities which bring other card(s) you own from outside the game into the game (such as Living Wish; Spawnsire of Ulamog; Karn, the Great Creator) do not function in Commander. In case your playgroup waives that rule and lets cards like Burning Wish search a mini sideboard or something, you should still not be able to violate your color identity and you should still not be able to bring a duplicate card into the game. Who's a good Demon Kraken?
This uses dependency (speaking of rules bugbears . In a Commander game, many playgroups use the rule that you can't bring cards in from outside the game, so anything that says you can get a card from outside the game just does nothing.
The companion ability has no effect if the card is in your starting deck. on April 10, 2020. I'm the rules manager, not the card police. Your companion is not one of your 100 cards. When we first saw the companion mechanic, our immediate reaction was “well, this is cool; it won’t work in Commander.” But, looking at the mechanic, there was nothing problematic about it. Once a Companion is brought into the game in this manner, it remains in the game until the game ends. For many players, the term "layers" fills their heart with dread, lurking in the shadows as a bizarre and arcane rules concept. The only issue was that the mechanic referred to outside the game.
That chosen companion doesn't start in your main deck; rather, it starts in your sideboard.
However, it's really describing a truth of linked abilities, not just copy effects, so I've moved it up to the linked abilities section and made it slightly more generic. When a card has a second name in the little box below the normal title bar, that second name is its real name. This is where we say that it was a one-time thing and we don’t expect it to happen again, but that might not be entirely accurate. Well, if you already know how trample works with damage doubling and damage prevention, anyway.
