Courier Griffin

The flying-body-plus-lifegain common is one of white's oldest workhorse templates, and this is a clean expression of it: a four-mana evasive blocker that pays back a small chunk of life on the way in. The 2/3 frame is the tell about who it was built for. It trades up against the two-power fliers and aggressive ground creatures of its color band, blanks a turn of attacks, and the two life is a cushion against the early race rather than a real swing. The whole point of a design like this is to give a deck a body that does two jobs at once from a single slot: it patrols the air and it nudges the damage-race math in your favor. Nothing here is meant to define a game on its own. The lifegain is incidental rather than build-around (there is no way to repeat it, no payoff stapled to it), which is exactly right for a card pitched at this rarity. It fills the curve, fills the air, and pads the life total margin, and asks nothing of your deck in return.
