Eluge's Flood Control

A mono-blue Standard Brawl control deck that uses Eluge, the Shoreless Sea to discount instants and sorceries while drowning the opponent in card advantage and countermagic.

Eluge gains flood counters each time you cast an instant or sorcery, so cheap spells like Opt, Spell Pierce, and Into the Flood Maw make later payoffs like Season of Weaving and Lunar Insight nearly free. Archmage of Runes and Kiora, the Rising Tide reward casting multiple spells with additional cards, while The Mindskinner and Riverchurn Monument give you an alternate mill win once you stabilize.

Keep a hand with two or three lands, at least one blue source, and either a cheap draw spell or a counterspell. Mulligan hands with no blue mana, hands full of expensive spells, or hands that cannot interact before turn four.

Early: hold up Negate, Essence Scatter, or Spell Pierce and cast Opt or Unsummon to stay alive. Mid: land Eluge and start reducing spell costs while drawing cards and bouncing threats. Late: chain discounted instants and sorceries for a huge Season of Weaving, refuel with Archmage of Runes and Kiora, then close with attacking fliers, The Mindskinner, or repeated mill.

Fast aggressive decks can pressure Eluge before the flood counters matter. Heavy discard and repeated commander removal can also reset the plan, so save protection and avoid overcommitting without backup.
