Oran-Rief Hydra
Most landfall payoffs ask you to count lands without fearing them: a counter here, a trigger there, scaling that rides whatever the deck already wanted to run. This Hydra reverses the math by paying double on the most common land in a green deck. Every land entry grows it, but a Forest doubles the return, and that bonus keys off the basic land type, not green mana. The distinction matters more than it first looks: a true dual land or a shock land that produces green carries the Forest type and triggers the doubled counters, so a fetch-heavy manabase pulling Stomping Ground or Bayou feeds the engine just as well as a stack of basics. The growth compounds with anything that drops a second land per turn or tutors one into play, since each entry is another trigger and each Forest is worth two. Trample is the half that converts those accumulated counters into damage rather than a chump-blocked stalemate; without it the body swells into a wall that a single token can hold off. The two abilities are inseparable. A 5/5 for six is unremarkable on the turn it resolves, which is the point: the question is what it becomes on the turns after, and the answer keeps climbing as long as the lands keep coming.
