Bristly Bill, Spine Sower

Green counters decks have always wanted a payoff that turns fixed, incremental growth into a single explosive threat, and this is the two-drop that finally puts both halves in the same body. The landfall half is the engine: every land drop is a +1/+1 counter, and because it targets any creature, it stacks that growth wherever it matters rather than forcing it onto Bill himself. That patience is what the activated ability cashes in. Doubling the counters on every creature you control is not a per-creature effect but a board-wide multiplier, so the value scales with how many bodies you have accumulated and how many counters you have already banked. The design tension is real: the ability costs , so the turn you double is a turn you are not developing, and a doubled board that gets swept loses everything at once. What keeps the card honest is that the payoff only pays what you have already built; there is no shortcut to a big board, only lands and time. The 2/2 frame is deliberately modest because the danger lives in the second line of text, and green rarely gets a repeatable counter-doubler attached to something this cheap. It rewards the slow accumulation green counters strategies were already doing and gives them a single button that converts all of it into a lethal turn.
