Tidal Barracuda

If an effect says that an opponent may cast a spell during your turn, Tidal Barracuda’s restriction overrules that permission.

Tidal Barracuda’s first ability doesn’t grant flash to any objects. It just changes when spells can be cast.

Tidal Barracuda’s abilities apply only while Tidal Barracuda is on the battlefield. Notably, its first ability doesn’t apply to Tidal Barracuda as you’re casting it.
