Waterspout Djinn

A 4/4 flyer for four mana was an aggressive rate in its day, and the upkeep tax is the discipline paying for it: every turn you keep this Djinn, you hand back an untapped Island, walking your own mana development backward one land at a time. That clock cuts both ways. Against a slow opponent the creature races them down before the land bounce matters; against anyone who can stabilize, the tax compounds until you either run out of untapped Islands or the board state no longer justifies the sacrifice. The design belongs to a family of Visions-era Djinns and efreets sold at a discount in exchange for a recurring upkeep cost, the rate-versus-friction bargain that defined a lot of mid-90s blue and red beaters. What makes this one quietly distinct is that the cost is land, not life or cards, so the build that wants it has to weigh an explosive early curve against a mana base that keeps eroding. Even if you spend your land drop replaying the bounced Island, you only break even on that Island's mana while spending the drop you would otherwise have used to grow; the cost is real because it taxes your development, not just your hand. Mostly, though, the card is a snapshot of a balancing philosophy that traded long-term stability for an above-curve body, and asked you to win before the bill came due.
