Aven Eternal

A flier that also builds the board it's flying over. Amass was the mechanic's answer to a token-parity problem: go-wide strategies tend to stall when every incremental payoff produces another separate body, each demanding its own attention and its own removal spell to answer. Amass instead pools that growth into one steadily larger Army, and this card contributes both a single counter's worth of that growth and a distinct evasive threat on top. The result is a piece that advances two axes with one trigger: it feeds the accumulating ground threat while flying over it as an independent clock. That doubling is the point, because concentrating value into a lone Army is a genuine liability on its own: a single kill spell that catches a large Army recoups every counter poured into it at once, the eggs-in-one-basket trade every wide deck fears. What keeps the strategy honest is redundancy from cards like this one, which hold their own body in reserve so a swept Army does not empty the board. The Zombie subtype the amass grants is the connective tissue, tying the Army to a tribe and to the graveyard-and-drain payoffs built to reward it. As a body in isolation it is a plain two-power flier; the design was never about the body, but about the way one entry trigger serves two boards at once.
