A-Metropolis Angel

The tell is in how narrowly the payoff is gated: the trigger fires only when your attacking force includes creatures already carrying counters, a condition that must be satisfied before the swing rather than during it. That front-loading pushes the card into decks that stamp marks on bodies cheaply and permanently: +1/+1 counter aggro, proliferate shells, anything that puts a counter on a creature and sends it in. What the design rewards is not attacking widely but attacking with the right creatures, and the distinction matters because a token swarm of empty attackers draws you nothing. The 3/3 flying body pays part of its own freight, since once something places a counter on it an evasive attacker can carry that counter and cash its own trigger. The structural interest is that this is a card-advantage engine bolted to the combat step rather than to an enters-the-battlefield trigger or a tap ability: it turns the decision to commit an attack into velocity, a steeper price than most draw engines charge, and it rewards a board built to survive the swing. This exists as an Arena-only rebalanced variant precisely because the untuned version paid out too freely for how little the counter requirement actually constrains a dedicated build; the digital tuning is a correction to a rate that outran its condition.
