Cloud Djinn

Six mana buys a 5/4 in the air, which the mid-90s priced as a genuine clock, and then the card hands part of that rate back: it can only block other fliers, so against the ground decks a six-mana blue creature most wants to stall, it defends nothing. That makes it a one-way threat dressed as a body that fights, attacking freely while leaving the dirt unguarded. The blocking clause was a recurring blue-and-white motif of the period, the same conversation that produced creatures forbidden from blocking entirely in exchange for a slightly sharper rate. This Djinn sits on the cautious side of that trade, paying full freight for evasion and accepting the restriction on top rather than trading the restriction away for a discount, which is why the rate never kept pace with what it was flying past. It belongs to the stretch when blue's expensive fliers were still negotiating their cost, before the color settled on tempo-positive evasive bodies that asked for nothing back.
