Kalastria Healer

The engine that turned the Ally tribe from a midrange goodstuff pile into a genuine drain combo. The body is irrelevant; what matters is that every Ally you flicker, recur, or simply play converts directly into a two-point life swing, and the rally trigger reads "each opponent," not "target opponent," so it scales with the table rather than picking one victim. Stack enough Allies and a single entrance becomes a multiple of that swing, which is where blink effects and untap-and-replay loops stop being cute and start being lethal: the card does not care how an Ally arrives, only that it arrives. That indifference to source is the whole design. Most aristocrat-style payoffs key off death triggers and demand a sacrifice outlet; this one keys off the cheapest, most repeatable event in the game, a creature entering the battlefield, and asks only that the newcomer share a type with the Allies already assembled. It is the closest the Ally mechanic ever came to a Blood Artist, drain on entry rather than drain on death, and it gave the tribe the one thing a pile of warm bodies otherwise lacked: an inevitability clock that does not require attacking.
