Merfolk are one of Magic's oldest creature types and are most closely associated with blue mana, islandwalk, and typal bonuses. Merfolk decks commonly combine inexpensive creatures with disruption before turning their aquatic army into evasive attackers.
Silvergill Adept provides efficient card advantage, while Kumena, Tyrant of Orazca converts a large collection of Merfolk into cards and +1/+1 counters. Emperor Mihail II can even cast additional Merfolk directly from the top of your library.
