This Bant Clue deck turns Morska, Undersea Sleuth's free upkeep Clue into a steady stream of draws. It cracks Clues and other draw engines to hit the second-card-drawn trigger every turn, which grows Morska and fires a suite of "second card" payoffs that make tokens and drop lands. Token doublers and Clue multipliers snowball the artifact count, and the resulting pile of artifacts and creatures pays for big spells through improvise and affinity and becomes an army. How it wins: It wins by flooding the board with tokens and pumped creatures, through Clues animated into 6/6s, mass pumps scaled by cards drawn, unblockable Detectives or a big Morska, while backup routes like Psychosis Crawler drain and Mechanized Production copying a Clue close out stalled games. Key roles: - Clue generation: Investigate effects on entry, on landfall, on deaths and on combat damage keep stacking Clue tokens beyond Morska, Undersea Sleuth's upkeep trigger, fueling both card draw and artifact count. (Tireless Tracker, Wavesifter, Ethereal Investigator) - Token multipliers: Doublers and replacement effects turn each investigate or token trigger into several tokens, exploding the Clue and creature count. (Adrix and Nev, Twincasters, Academy Manufactor, Erdwal Illuminator) - Second-draw payoffs: Cards that trigger on the second card drawn each turn, alongside Morska, Undersea Sleuth's counters, make creature tokens or put lands into play every turn the deck cracks a Clue. Draw doublers make those triggers easy to reach. (Alandra, Sky Dreamer, Detective of the Month, Teferi's Ageless Insight) - Artifact mass as resource: The large artifact count casts expensive spells cheaply through improvise and affinity, taps for cards, and grants hexproof or evasion. (Inspiring Statuary, Kappa Cannoneer, Shimmer Dragon) - Clue army and pump finishers: Clues become 6/6 creatures, Equipment or exalted sources, and team pumps scale with cards drawn or hand size to turn a wide board into lethal. (Tangletrove Kelp, Knowledge Is Power, Armed with Proof) - Alternate kills and sacrifice value: Clue sacrifices gain life or make bodies, every draw drains opponents, and copying an artifact each upkeep threatens an outright win. Sweepers reset boards while the deck's Clues stay on the battlefield, since Fumigate and Organic Extinction only hit creatures. (Psychosis Crawler, Mechanized Production, Ulvenwald Mysteries)
