Centaur Glade

Token engines survive the things that kill creatures, and that durability is the entire bargain on offer here: spot removal picks off one Centaur and leaves the enchantment humming, board wipes reset the count without reaching the source. Pay five up front for a permanent that sits inert when it resolves, then convert excess green mana into 3/3 bodies every turn you have the spare lands. The activation is deliberately heavy: each token wants nearly half a developed mana base, so the board never floods at once and the engine stays a top-end payoff rather than a midgame snowball. That cost is what keeps it fair. It belongs to an older school of mana sink, the design that turned a stalled green board and a flush of untapped lands into a slow, attrition-proof clock. The threat is the factory, never any single Centaur; an opponent who runs out of answers before you run out of mana simply loses to arithmetic. Hold the board early to protect the investment, then grind out a token a turn once the coast is clear. It rewards reaching the late game with land to spare, and punishes a deck that planned to win before then.
