Monastery Flock

Cast it face down and it stops being a defensive card at all: a blank 2/2 with no restriction, free to swing across an unguarded board and bank two or three damage while your opponent has no idea what they are blocking. That anonymity is the point. The real body is a 0/5 flier that Defender locks out of attacking, a stonewall against both ground assaults and small aerial threats, but you get to choose when to reveal it. For a single blue you flip it face up, often mid-combat: ambush an incoming flier, or convert your early beater into a permanent wall once its damage is in. The same physical card serves as an early clock and a late-game blocker depending on which face is showing, which is why a creature with zero offensive upside in its true form still earns a slot. It is rarely a dead draw, because the face-down mode always demands a block or gets in, and the cheap flip cost means turning it up is almost never a meaningful tax. This is the durable, unglamorous end of morph: not a blowout hiding behind a face-down card, but a flexible body answering two different problems with one draw, asking only that you read combat correctly to time the reveal.
