Dream Prowler

A defensive body that smuggles in an evasion clause, and the tension between those two halves is the whole design. A 1/5 wants to sit back and trap attackers; the unblockable rider only fires when this thing attacks by itself, with no other creatures joining the assault. So the card asks you to choose a mode each turn rather than handing you both. As a wall it is genuinely sturdy, soaking up most of the era's aggression; as a clock it nudges in a single unanswerable point at a time. That gulf between toughness and power is the point: the body survives the offense it is meant to deter, then occasionally walks one damage past it. The "attacking alone" restriction is the pressure valve that keeps the unblockable text from being a free finisher. You cannot crash the board and slip this through in the same swing; commit it to the attack and your other creatures stay home. It is a slow, almost contemplative beater, the kind of incremental inevitability blue has always preferred to brute force, wrapped around a stat line that lets it bide its time until the alone-attack window opens.
