Tevesh Szat, Doom of Fools

For the second ability of Tevesh Szat, Doom of Fools, you choose whether to sacrifice anything and what to sacrifice as the ability resolves.

An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.

Once the game begins, your two commanders are tracked separately. If you cast one, you won't have to pay an additional {2} 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.

You 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.

If you leave the game, each commander you gained control of is returned to its previous controller's control. Each commander that entered the battlefield under your control is exiled (from there, its owner may return it to the command zone).

As the third ability is resolving, you'll gain control of all commanders that were already on the battlefield before the commanders from the command zone enter the battlefield under your control.
