Armix, Filigranschmetterer

• 10.11.2020An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
• 10.11.2020If a creature is attacking a planeswalker, that planeswalker's controller is the defending player.
• 10.11.2020If your Commander deck has two commanders, you can only include cards whose own color identities are also found in your commanders' combined color identities. If Falthis and Kediss are your commanders, your deck may contain cards with black and/or red in their color identity, but not cards with green, white, or blue.
• 10.11.2020Armix's ability goes on the stack without a target. While that ability is resolving, you may discard a card. If you do, a second ability triggers and you pick one target to get -X/-X. This is different from abilities that say "If you do . . ." in that players may cast spells and activate abilities after you've discarded a card but before the creature gets -X/-X.
• 10.11.2020The value of X is determined only as Armix's ability resolves. Once that happens, the value of X won't change later in the turn, even if the number of artifacts in your graveyard and under your control changes.
• 10.11.2020Once the game begins, your two commanders are tracked separately. If you cast one, you won't have to pay an additional the first time you cast the other. A player loses the game after having been dealt 21 damage from any one of them, not from both of them combined.
• 10.11.2020If 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.
• 10.11.2020If the discarded card is an artifact card, it will be counted as you determine the value of X, provided it's still in the graveyard or, optimistically, on the battlefield under your control at that time.
• 10.11.2020You can choose two commanders with partner that are the same color or colors. In Commander Draft, you can even choose two of the same commander with partner if you drafted them. If you do this, make sure you keep the number of times you've cast each from the command zone clear for "commander tax" purposes.
• 10.11.2020To 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.
• 10.11.2020While resolving Armix's ability, you can't discard more than one card to give more than one creature -X/-X.
• 10.11.2020Both 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.
