Sporesower Thallid
Most of the Thallid line is fragile fodder: small bodies that exist only to bank counters and convert time into Saprolings. This one breaks that pattern with a 4/4 that holds the ground while the engine warms up, and more importantly with an upkeep trigger that does not just feed itself. It seeds a counter onto every Fungus you control, turning a board of otherwise-passive mushrooms into a synchronized clock. Field two or three and the counters stack additively, collapsing the wait so the whole tribe starts producing 1/1s well ahead of any single Fungus's natural pace. That shared trigger is the design pivot that made this creature the linchpin of the green token-grind strategy the Thallids were built around: it scales the entire apparatus rather than just itself. The cost structure keeps the engine deliberately slow, though. A counter ticks on one increment per upkeep, and each Saproling drains three of them from the producer, so a lone Sporesower keeps you on a fixed drip measured in turns, not mana. The deck's whole project is fielding enough Fungi that the upkeep trigger compounds across the board faster than any one creature could manage alone, with the 4/4 frame buying the patience that the rest of the tribe cannot.
