Glimpse the Cosmos

Impulse-style card selection is old and well-priced, but this one bolts a tribal reload onto it: the recast clause turns the graveyard into a repeatable dig engine, so long as a Giant is on the board to unlock it. The two-mana cast filters three deep and keeps the best card; the buyback discount then lets you spend a single blue to run it again from the yard, with an exile clause that caps the loop at one extra use per copy. That structure is the whole tension. Without a Giant, it is a slightly-below-rate cantrip that finds you a card and vanishes. With one, it becomes a mana-cheap way to convert flooded turns into fresh cards, smoothing the draws in a Giant-tribal shell whose payoffs tend to sit high on the curve and stack up uncastable. The Giant condition does double duty: it gates the recast so the effect isn't just free value in any blue deck, and it ties selection to a creature-type theme that otherwise leans on expensive, top-heavy bodies. Card advantage engines that hinge on a specific tribe are a narrow design lane, and this one lives or dies by whether the board supports it; the payoff is that a Giant-heavy build gets a card-selection tool that refuses to stay dead in the graveyard.
