During turns other than yours, spells you cast cost 1 less to cast.
Rulings
One official ruling, as Wizards published it.
- 2024-11-08
To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
