Deserter's Disciple

Evasion-granting has always come cheap when it stays on a stick, and this is the sticky version: a repeatable tap ability that makes one small attacker unblockable every turn, no mana required. The power-2-or-less clamp is the whole balance, aiming the card at exactly the board it wants to live on: a wide swarm of one- and two-drops where the threat isn't any single creature but the accumulation of connections. Note the ability targets another creature, so it can't push itself through, which keeps the 2/2 body honest as a blocker or a chump rather than a self-sufficient clock. The interesting friction is the tap cost against a summoning-sick body: this is a build-around that pays off a turn late, rewarding a board already developed rather than one you're still assembling. Where the effect earns its keep is on creatures whose whole reason for connecting is a trigger the defender would rather eat than take: a pinger, a drainer, a saboteur that mills or draws on damage. In that shell the small-power restriction stops being a limit and becomes a filter for exactly the kind of creature you'd want unblockable anyway.
