Moon Heron
Few stat lines have been reprinted as often, across as many colors and creature types, as the four-mana 3/2 flyer, and this Spirit Bird is a clean representative of the benchmark. The arithmetic is deliberately ordinary. A 3/2 in the air pressures a life total fast enough to matter, dies to almost any burn spell or unfavorable trade, and costs exactly enough that copies cannot crowd out the rest of a curve. That fragility is the whole balancing act: it threatens roughly seven swings of damage but folds to a single piece of interaction, so the live question every game is whether the answer arrives before the clock does. The body sits at a precise midpoint in common-rarity flier design, relevant enough to anchor a skies-based plan yet interchangeable enough that nothing breaks when it trades down. The Bird typing is era-appropriate flavor, but the card's real identity is structural: a repeatable measure of what evasion should cost when a set wants the air contested without making it the only axis games are decided on. Designers reach for cards like this not because they excite but because they are calibrated, the floor against which more ambitious fliers get priced.
