Evolution Sage

Landfall and proliferate both existed for years before this Elf Druid welded them onto one cheap green body, and that welding is the whole trick: it turns proliferate from an occasional tacked-on mode into a rhythm you hit every land drop. Because fetch lands and extra-land effects can stack several lands into a single turn, the count-up stops being a one-time bump and becomes an engine that advances every counter on the board at once. That reframes what proliferate is worth: planeswalker loyalty, +1/+1 counters on a token army, poison and infect, charge counters on artifacts, even saga chapters all move forward without spending a card or an activation. The 3/2 body is where the tension lives; it has to survive to matter, and the payoff only compounds across multiple land drops, so protecting a fragile druid becomes the price of the engine rather than deploying it as a threat. The counter-agnostic wording is what gives it range: it does not care which kind of counter it proliferates, which means the same three-mana creature slots into a superfriends shell, a +1/+1 counters deck, and an infect build without a word of its text changing. The observation that makes it a keystone rather than a role-player is small and precise: two decade-old mechanics, one green creature, and a trigger that fires on the most frequent event in the game.
