Hydromorph Gull

Protection wearing the body of a flier. The defensive proposition here is narrow but absolute: it intercepts removal aimed at your creatures by countering the spell outright, so the threat keeps living rather than scraping by as a worse target. The sacrifice clause does the balancing work. You pay the bird and a blue mana to neutralize one targeted spell, and once it leaves, your protection leaves with it, so the card answers a single point of pressure rather than standing guard indefinitely. The target restriction is the catch: it only catches spells that target a creature you control, so it does nothing against sweepers, edicts, or removal pointed elsewhere. Within that lane it is precise. An aura-laden monster, a tempo-critical evasive threat, a combat-relevant creature on the brink of a fight: at five mana the Gull arrives as a 3/3 flier that pressures on its own, then holds the counter in reserve until the opponent commits a kill spell to the stack. That is the quiet efficiency of the design. The protection is not a static keyword bolted to a creature; it is a one-shot counterspell with wings, parked on the board and cashed in at the exact instant a targeted removal spell goes on the stack. The card lives or dies on patience: hold the sacrifice through every minor exchange and spend it only on the answer that decides the game.
