Chocobo Racetrack

The clever part is the recursion inside the recursion: the trigger reads off every land drop, and the bird it makes carries that same trigger. Each fetch, each extra land drop, each landfall payoff you were already running now spawns a body and pumps the entire flock at once, because every land entering fires every bird's +1/+0 clause simultaneously. So the payoff scales quadratically without saying so on the card. One land under one bird is a small nudge; three lands with four birds on board is a combat step that ends games. That structure ties it to a familiar green tension: the deck wants to slam extra lands anyway, and this rewards the thing green was going to do regardless. What keeps it from being a token-swarm engine on the cheap is the five-mana artifact shell with no board impact when it resolves. It builds toward a payoff over successive turns rather than swinging a race the moment it hits play, so it wants a manabase built to keep dropping lands and a game that goes long enough for the birds to matter. In a color that has always struggled to convert ramp into a threat count, this converts the ramp itself into the threat, which is a quietly different job than most green landfall cards take on.
