Repeat — Riftbound Rules

820.1.

Repeat is an Optional Additional Cost keyword.

820.1.a.

Repeat is present on Spells and Abilities.

820.1.b.

Repeat is an optional cost that a player may pay to execute the effect of their spells and abilities a second time.

820.1.c.

Repeat is formatted as “Repeat [Cost]”

820.1.c.1.

The Cost is an Additional Cost to be paid during the steps of playing the spell or ability.

820.1.c.2.

If a spell or ability has more than one instance of Repeat, each Cost may be paid or not paid individually.

820.1.c.3.

Each Repeat Cost can be paid only a single time.

820.1.d.

Repeat is functionally short for “You may pay [Cost] as an additional cost as you play this. If you do, execute the instructions of this chain item one additional time during resolution.”

820.1.d.1.

When the additional cost is paid, the effect of the spell or ability, upon resolution, will be performed an additional time. Example: Desert’s Call is a spell with [Repeat] [2] and “Play a 2 [M] 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 [M] Sand Soldier unit token. Play a 2 [M] Sand Soldier unit token.” Example: A unit reads in part “When I attack or defend, you may deal damage equal to my Might to an enemy unit here,” and “My abilities have [Repeat] — Discard 1.” When its ability triggers, if its controller pays the Repeat cost as they play it, the ability’s instruction to deal damage equal to the unit’s Might is executed twice, as though the ability says “Deal damage equal to my Might to an enemy unit here. Deal damage equal to my Might to an enemy unit here.”

820.1.d.2.

Any instructions not performed on resolution of the spell or ability are ignored.

820.2.

When a spell or ability’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 349. Playing Cards for more information.

820.2.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.

820.3.

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

820.3.a.

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

820.4.

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

What costs does Ezreal, Prodigy reduce? Does he reduce Repeat costs? Accelerate costs? Equip costs?

Ezreal reduces optional additional costs using both "additional cost" and "may." Repeat and Accelerate qualify, but not Equip costs - that's an activation cost for an ability, so it's neither optional nor additional.

What parts of a spell does the Repeat ability cause to be repeated? Is it the entire effect? If I use Temporal Portal to give Find Your Center Repeat and pay the cost while its cost reduction applies, does the cost reduction happen once or twice, and does the final spell cost 2 or 4?

Repeat causes repetition of a spell's instructions. Find Your Center's cost reduction applies once, making the final cost 4 - its base cost of 3, plus its Repeat cost of 3, minus its cost reduction of 2.
