Aegis Turtle

A wall in the classic sense: five toughness for a single blue mana, no offensive pretense, no evasion, no upside beyond the body itself. That toughness-to-cost ratio is the entire pitch. Blue rarely gets to buy this much defense this cheaply, and the reason it can is that the card contributes nothing to a proactive plan. It sits in front of an aggressive board and refuses to die to the usual small-creature beats, blanking two- and three-power attackers indefinitely while its controller sets up the slower game blue actually wants to play. The 0 power is the honest cost: it never trades up in combat, never pressures a planeswalker, never closes a game. It is pure time. In a color built around answering threats a turn late rather than racing them, an early speed bump that survives most burn and shrugs off the first waves of a curve-out is precisely the kind of tool that lets a control or ramp shell reach the turns where its real cards take over. Turtles as a defensive creature type are almost self-parody, and this one leans all the way in: no tricks, no toughness matters payoff hiding in the text, just a shell that outsizes nearly everything trying to swing through it in the opening turns of a game.
