Jade Orb of Dragonkind

Ramp that launders its mana into a tribal rider: tap it for green, and if that green pays for a Dragon creature spell, the Dragon lands with an extra +1/+1 counter and hexproof through your opponents' next turn. What's worth clocking is where the payload lands. The protection does nothing for the spell on the stack (a Dragon cast off this mana still eats counterspells like anything else), and it does nothing against a board wipe that doesn't target. Its window is narrow and precise: the moment a fresh Dragon resolves onto an empty-ish board, when a single targeted removal spell in response is the cheapest, cleanest answer an opponent has. That's the exact interaction hexproof shuts off, and because the shield persists until your next turn rather than firing once, it blankets a full cycle of instant-speed spot removal before the Dragon can be answered on fair timing. The counter is incidental scaling; the real function is buying a marquee threat one clean turn to matter. It sits among a handful of ramp pieces built to reward routing their mana into one creature type, where the generic fixing is the floor and the tribal rider is what justifies the slot over a plain rock. Absent a critical mass of Dragons, it collapses back into a slow source of one green.
