Hada Spy Patrol

Level Up asked creatures to grow in discrete, paid-for steps rather than from a single counter or an aura, and this Rogue spends that incrementalism on a slow-rolling evasion threat. The first activation buys the whole payload: a 2/2 that can't be blocked, which is everything the card needs to start a clock for the cost of the body plus one investment. The third tier is insurance rather than escalation. It bumps the body to a 3/3 and, more to the point, drapes shroud over it, so the unblockable attacker that has been chipping away becomes one your opponent can no longer touch with spot removal, edicts and sweepers aside. The sequencing is where the design tells: because leveling is sorcery-speed, you spend mana proactively on your own turn building toward the next attack, so the patrol rewards a tempo position where you can commit mana forward rather than holding up interaction. Since the creature can't be blocked at either leveled tier, combat never answers it; the top end strips away targeted removal too, narrowing an opponent's outs to a board wipe or an effect that does not target. It is a modest threat paid for in installments, and the reward at the top is a clock that is both untouchable and unblockable.
