Tam, Observant Sequencer // Deep Sight

Every land drop rearms the front half, turning the 4/3 into a battery that discharges a fresh copy of Deep Sight each time a land enters under your control, tapped or not. That cadence is the point. Prepared works as a slower, on-the-battlefield relative of flashback: rather than recurring a spell from your graveyard, you charge the creature and cast a copy of its spell while the body stays in play, so the payoff is not a one-shot but a resource you regenerate one land at a time. Cast Deep Sight, unprepare, play a land, repeat, and you have a repeatable cantrip-and-lifegain loop that leaves your library alone until you actually spend the trigger. The split between the two halves is the shrewd part. The 4/3 clocks on its own, so the prepared spell reads as upside rather than a tax to make the creature functional; you are never holding an inert rock waiting to fire. Deep Sight stays deliberately small (one card, one life) because the value lives in frequency, not size. A meatier payoff attached to a trigger you can hit more than once a turn would spiral fast, so the reward is calibrated to a steady drip of lands rather than a single explosive turn. It is a green-blue value engine that treats land drops as fuel and measures how long you can keep the machine running.
