Aerial Responder

Three keywords stacked on a 2/3 for three mana, and the choice of which three is the whole design intent. Flying, vigilance, and lifelink form a particular triangle: the flyer can attack without surrendering the ground, and every point of combat damage it deals (whether swinging in the air or clocking a blocker it survives) refills your life total. That makes it a body built to grind, not to race. It does not end games quickly and it does not trade up against real removal, but in a stalled board it widens the life gap every turn it connects while still sitting back to hold the ground. The lineage runs through cards like Serra Angel, the flying-and-vigilance white midrange anchor of an earlier era; this trims the stats and the cost, swaps in lifelink, and lands at a tighter, cheaper point on the same curve. The 2/3 toughness is the quiet load-bearing number: it survives the most common cheap red burn and squares off favorably against the small attackers it was made to hold off, which is exactly what lets the vigilance pay rent on defense while the flying earns it on offense. Nothing about it is flashy, but the keyword combination is internally consistent in a way a lot of multi-ability creatures are not: each ability makes the other two better instead of competing for the same combat step.
