Falkenrath Exterminator

A snowball engine bolted to the flimsiest possible chassis. The two halves feed each other: each unblocked attack adds a single +1/+1 counter, and the activated ability scales off exactly that count, so the same connection that grows the body also widens the gun it can aim at the rest of the board. The trouble is the cost of admission. A 1/1 that has to land combat damage before it does anything is asking a lot from a board full of removal and blockers, and at that size it dies to the very ping effects it eventually wants to dish out itself. Get it through a few times, though, and the math inverts: a body sitting on three or four counters becomes a repeatable removal outlet, paying a turn to snipe whatever the opponent develops while it keeps accreting counters on the swing. The whole design lives on that knife-edge between worthless and runaway, with no haste, no protection, and no evasion to bridge the gap, which is why it wants equipment, an anthem, or a board already tipped in your favor. The linear counter growth is the reward, but the reward is locked behind its own setup problem: you have to keep a defenseless two-drop alive and connecting turn after turn before the engine ever turns over.
