Reyhan, Last of the Abzan
Oracle Text
Reyhan, Last of the Abzan enters the battlefield with three +1/+1 counters on it.
Whenever a creature you control dies or is put into the command zone, if it had one or more +1/+1 counters on it, you may put that many +1/+1 counters on target creature.
Partner (You can have two commanders if both have partner.)
Card Rulings
11/8/2016 If enough -1/-1 counters are put on a creature at the same time to make its toughness 0 or less, the number of +1/+1 counters on it before it got any -1/-1 counters will be used to determine how many counters you put on target creature. For example, if there are three +1/+1 counters on Reyhan and it gets six -1/-1 counters, the target creature gets three +1/+1 counters.
11/8/2016 If 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 Akiri and Silas Renn are your commanders, your deck may contain cards with white, blue, black, and red in their color identity, but not green.
11/8/2016 Both commanders start in the command zone, and the remaining 98 cards of your deck are shuffled to become your library.
11/8/2016 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.
11/8/2016 Once 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 one of them, not from both of them combined. Command Beacon’s effect puts one into your hand from the command zone, not both.
11/8/2016 An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
- Khans of Tarkir: Present-day Tarkir, where and when Sarkhan Vol was born, all Dragons extinct.
- Fate Reforged: Sarkhan, the Dragonspeaker travels back in time to when Khans and Dragons existed together on Tarkir, fighting for territory (Citadel Siege). Sarkhan saves Ugin, the Spirit Dragon from death after witnessing him battle Nicol Bolas, Planeswalker (Crux of Fate), then Sarkhan jumps back to the present-day in Tarkir. By saving Ugin, Sarkhan irreversibly alters Tarkir's timeline. Sometime after this, Dragon storms (I believe where Dragons are born) intensify all across Tarkir, and Dragons become more powerful than Khans, eventually overthrowing the Khans in the story "Khanfall". This story is depicted in Reyhan's art, showing her as the last leader of the resistance against the Dragons, after Daghatar the Adamant surrendered the majority of the Abzan to Dromoka, the Eternal.
- Dragons of Tarkir: Present-day Tarkir, completely replacing the Khans of Tarkir reality. In this Tarkir, Dragonlords rule (Dragonlord Dromoka), and only Sarkhan Unbroken remembers that this timeline used to be ruled by Khans.
