Angel of Mercy

The textbook example of "creature plus a life cushion," and the design that helped name the lifegain-on-a-stick template in player vocabulary. The math is the lesson: a 3/3 flyer is a fair body for five mana, and the three life is the rate's gentle premium, a buffer that buys a turn against an aggressive board without ever closing a game on its own. That restraint is the point. The life arrives once, on entry, with no recursion and no engine attached, so the card teaches a new player to value tempo and stabilization separately rather than expecting a single creature to do both. Originating in the Portal line, those stripped-down introductory products built for newcomers, it carries the design DNA of those sets: every word does instructional work, nothing demands a rules lookup, and the flavor of an angel arriving to grant grace maps cleanly onto the mechanic. The flying body and the lifegain reinforce each other thematically without interacting mechanically, a legibility those teaching sets prized above all. White has since printed dozens of variations on the entry-trigger-lifegain skeleton at sharper rates and with deeper synergy hooks, but this is the clean ancestor: the rate stripped to its honest components, with the angel doing the flavor lifting and the three life doing the math.
