Azorius Knight-Arbiter

The 2/5 body is the entire argument here. Unblockable creatures usually come cheap and fragile: the archetype leans on evasion to squeeze in a few points before dying, so the body is priced to break through, not to survive. This one inverts that instinct. It cannot be blocked, but its two power means it is never racing anyone down; instead it grinds, chipping the same two damage turn after turn while a five-toughness back end shrugs off most burn and combat retaliation. Vigilance is the piece that makes the math close: the arbiter attacks unopposed and still stands as a wall against whatever comes back, so committing it to the red zone costs nothing defensively. The result is a creature built for the long game rather than the fast one, a clock you set down and stop worrying about, dependable in the way a leak is dependable. It is a deliberately unglamorous read on evasion, one that trades the highlight-reel alpha strike for a body that keeps ticking and refuses to trade, which is exactly the kind of attrition tool a control-leaning white-blue deck wants when it needs damage to arrive without ever exposing itself.
