Rulings (2)
- Brineborn Cutthroat's ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
- Brineborn Cutthroat must be on the battlefield for its last ability to function. Notably, the ability won't trigger as you cast Brineborn Cutthroat during an opponent's turn.
