Archon of Redemption
The lifegain here is built to scale with the deck around it, not with the Archon itself. Each flier you land, including this one entering for three life, pays out life equal to that creature's power, which means the payoff lives in the bodies you commit, not in any single trigger. A board of small evasive creatures turns it into a steady drip; a single fat flier turns it into a lump-sum buffer the moment it arrives. The 3/4 frame is the giveaway: this is not a beater asking to carry a game, it's an anchor that wants company in the air. Wide flying strategies are the obvious home, but the design also rewards reanimation and blink decks that can re-trigger entries, since the ability fires on each qualifying creature entering rather than once per turn. The ceiling depends entirely on how much evasive power you can stack, which is the discipline that separates it from white's flat "gain life when this attacks" history: the trigger reads the power of whatever shares the skies, so the deck decides the rate. On its own it is a fine flier that buys back a few life on the way down; surrounded by a committed air force, the cumulative gain can outpace what an aggressive opponent can claw back. That conditional payout, tied to board state rather than to a fixed number, is what gives the card its texture.
