Namor, Scourge of the Seas
Leverage Namor's connive trigger each combat to sculpt your hand and spread +1/+1 counters across your Merfolk squad, granting them flying and proliferating those counters to overwhelm opponents from above.
Asked for“Namor, Scourge of the Seas, build a blue Merfolk deck that stacks +1/+1 counters on your Merfolk so they gain flying, and connive a creature every combat to keep looting toward a legion of airborne fish-people.”
Deck anatomy
What this list actually runs on: how cheaply it casts things, and whether it has enough ramp, card draw and interaction to keep up at the table. Each block is one card — hover for its name.
Mana curve · 61 nonland cards
The working parts
Counted from Scryfall’s community card tags, not from the builder’s own labels. A card that does two jobs counts twice, so these add up to more than the deck. The hatched band is a common rule of thumb, not a law — combo decks run leaner, battlecruiser decks heavier.
