746. Repeat

746.1. Repeat is an Optional Additional Cost keyword.

746.1.a. Repeat is present on Spells.
746.1.b. Repeat is an optional cost that player may pay to execute the effect of their spells a second time.
746.1.c. Repeat is formatted as “ Repeat [Cost]”
746.1.c.1. The Cost is an Additional Cost to be paid during the steps of playing the spell.
746.1.c.2. If a spell has more than one instance of Repeat , each Cost may be paid or not paid individually.
746.1.c.3. Each Repeat Cost can be paid only a single time.
746.1.d. Repeat is functionally short for “You may pay [Cost] as an additional cost as you play this spell. If you do, execute the instructions of this spell one additional time.”
746.1.d.1. When the additional cost is paid, the effect of the spell, upon resolution, will be performed an additional time. Example: Desert’s Call is a spell with [Repeat] [2] and “Play a 2 [S] Sand Soldier unit token.” If its controller pays its Repeat cost as they play it, the card’s instruction to play a Sand Soldier is executed twice, as though the card says “Play a 2 [S] Sand Soldier unit token. Play a 2 [S] Sand Soldier unit token.”

746.2. When a spell’s effect is performed an additional time with Repeat , choices must be made at the usual time during the Make Relevant Choices step of Playing a Card. See rule 346 Playing Cards for more information.

746.2.a. Choices made for the additional execution do not have to be the same as the choices made for the initial execution. Example: Rocket Barrage is a spell with [Repeat] [4][C] and “Choose one — Deal 4 to a unit in a base. [or] Kill a gear.” If Rocket Barrage’s controller pays its Repeat cost as they play it, they may choose the same mode or a different one, and if they choose the same mode, may choose the same target or a different one. If they choose “Kill a gear” twice and choose two different gear, they must specify which gear is the first target and which is the second. As the spell resolves, those two gear will be killed in the chosen order.

746.3. Multiple instances of Repeat can be paid for separately. The spell’s instructions will be executed an additional time for each instance of Repeat that is paid for.

746.3.a. Regardless of the number of times a spell's instructions are executed with this keyword, the spell is only Played once.

746.4. Repeat , and whether or not a spell has Repeat , is a characteristic of the Spell and may be checked or referenced by other Game Effects.
