Lifegain that compounds: each Ally you play, including this one as it arrives, pays out life equal to your total Ally count, so the engine accelerates as your board widens. A lone copy gains a single life and stands around as a 1/1, but the curve bends sharply the more bodies you stack: a fourth Ally entering is four life, a sixth is six, and a refilled board after a wipe can recoup a brutal sum in a single chain of plays. That self-counting trigger matters: because the creature's own entry registers, it is never a blank when it lands. The cost of all that scaling is its total dependence on critical mass. This contributes nothing as a standalone threat and only generates real value inside a deck committed to flooding the table with its tribe, which is exactly why a ceiling this runaway could sit at common. The floor is honest payment for the ceiling: a 1/1 with no reach or evasion, useful only as a node in a wider lifegain engine, demanding reinforcements before it does anything that matters.
