Deck overview

This deck is a Mono-Blue Control and Combo strategy that leverages efficient card draw, robust stack interaction, and artifact ramp to assemble infinite mana combos. Helmed by Keiga, the Tide Star, the commander serves as a late-game deterrent and creature theft engine, while the deck's primary focus is resolving decisive combos. Key engines include Isochron Scepter paired with Dramatic Reversal and Basalt Monolith paired with Forsaken Monument or Rings of Brighthearth. Once infinite mana is generated, the deck draws its library with Clues from Forensic Gadgeteer or loops with Hullbreaker Horror and Tidespout Tyrant to bounce all opposing permanents, finishing opponents in the same turn via Blasting Station or Altar of Dementia. A dense suite of premium free and low-cost countermagic ensures both resilience and reliable disruption throughout the game.
