Auntie's Snitch
Prowl's central conceit was that connecting in combat with the right creature type discounts your next spell, and most of the cycle simply rewarded you for having already started the beatdown. This Goblin Rogue takes that loop one step further by writing recursion into its own body: the trigger fires whenever any Goblin or Rogue you control deals combat damage to a player, and if it is sitting in your graveyard, it climbs back to your hand for free. That turns a 3/1 into a renewable resource. Trade it in combat, chump nothing (it can't block, so it was never going to anyway), then recur it off the next attacker and recast it at the prowl cost of . The body is built to die and come back rather than to survive, which is why the can't-block clause is a feature rather than a tax: it commits the card to the attacking step, the only phase where the engine pays out. The result is a self-fueling pressure piece that wants a wide Goblin or Rogue board to keep the recursion trigger live, and a low-curve aggressive shell that can actually afford to keep recasting a one-toughness creature. The design rests on a quiet inversion: a creature can stay cheap precisely because it never really leaves. The graveyard becomes a holding pen, and combat is the key that lets it out again.
