Spined Megalodon

The seven-mana hexproof beater is a curve-topper built for the exact moment a game has gone long and nobody has drawn their answer. Hexproof on a body this size is a specific kind of promise: no targeted removal, no bounce, no aura theft, because none of it can find the creature in the first place. The keyword has honest gaps, though, and they are the tax that keeps a 5/7 for seven from being oppressive: a board wipe still catches it, and an edict still forces it to the graveyard because that effect targets you, not the Shark. Within those limits it is remarkably hard to answer one-for-one. The 5/7 body is deliberately shaped for the grind, the toughness outrunning most red burn while the power carries a real clock. The scry on attack is the quiet part that earns the slot: a creature this expensive should not merely swing, so every declared attack digs one card deeper toward the land you are stuck under or the payoff you are hunting for, whether or not the attack connects. That turns a lone threat into a slow filtering engine. This is common-rarity blue's version of an inevitability card: no evasion, no protection racket beyond the hexproof, just a large untargetable body that smooths your draws each combat and asks for nothing in return except the seven mana to cast it.
