Metropolis Angel

The trigger reads as generic Azorius card advantage until you notice how narrowly it's fenced: it fires only when your attackers include something with a counter on it, which turns a flying beater into the payoff for a whole deckbuilding thesis rather than a standalone value engine. That condition is what you pay for the effect. A blank battlefield draws nothing; a board seeded with +1/+1 counters, or a lone token minted with a counter, converts every combat step into a card. The design lives on a specific axis: it rewards counters as a resource category regardless of how they arrive, whether from proliferate, adapt, mentor-style combat placement, or a mutating pile, so it slots into a counters-matters shell without demanding any particular enabler. The draw is deliberately capped, though. It keys off the attack step and asks only that one or more counter-bearing creatures swing, so a wide alpha strike still nets exactly one card, not one per attacker. That ceiling is what keeps the effect from spiraling: it wants you attacking every turn to bank incremental cards, not staging a single blowout swing that refills your whole hand. The 3/1 body reinforces the same intent, evasive enough to peck in but too fragile to trade, which pins the Angel where its designers wanted it, at the head of a proactive board grinding out one card at a time rather than hiding behind a control shell.
