“Sygg, River Guide” is a blue and white Merfolk with the ability to give Merfolk protection from a color.
Similar cards (Azorius/Blue-White Merfolk leaders or protectors):
- “Sigarda, Host of Herons” (provides protection, different tribe)
- “Lavinia of the Tenth” (Azorius, detains creatures)
- “Thrasios, Triton Hero” (Blue-Green, Merfolk, not protection but card/filtering)
- “Brago, King Eternal” (Azorius, flickers your creatures for pseudo-protection)
- “Derevi, Empyrial Tactician” (Bant, but includes blue/white, unique protection via tapping)
No other Merfolk gives the same protection, but these are close in Azorius colors or tribal support.
