Namor control

Azorius Merfolk Control in blue-white (with a light red splash via Raugrin Triome) that plays like a tempo-control deck. It combines the classic Merfolk shell—Aether Vial, Silvergill Adept, Vodalian Hexcatcher, Tide Shaper, Mutavault, and Cavern of Souls—with a strong interactive control package like Counterspell, Archmage’s Charm, Force of Negation, Prismatic Ending, March of Otherworldly Light, and Teferi, Time Raveler.

The deck aims to disrupt the opponent early, develop efficient flash/Vial-powered threats, and then protect its board with countermagic while chipping in for damage. Hexcatcher and other Merfolk create soft lock pressure against opposing spells, while Narset and Teferi help shut down card draw and instant-speed interaction. It usually wins by incremental combat damage from Merfolk and Mutavault after gaining control of the game.
