Temporal Portal

gear

rune rainbow, exhaust: Give the next spell you play this turn [Repeat] equal to its cost. (You may pay the additional cost to repeat the spell's effect.)

Rulings

• 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?
