T: Target Merfolk creature can't be blocked this turn.
Rulings
One official ruling, as Wizards published it.
- 2009-10-01
To have any effect, Merfolk Sovereign's activated ability must be activated before the declare blockers step begins. Once a Merfolk has become blocked, activating Merfolk Sovereign's ability won't change that.
Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Merfolk Sovereign — a name search across every version, for the printings TCGplayer publishes no direct link to.
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.
