Crawling Sensation
The trick here is that the upkeep mill is not where the engine actually lives: milling two cards is just one trigger source among many, and the token clause counts a land hitting your graveyard from anywhere, not just from the top of your library. That "from anywhere for the first time each turn" wording is the whole point. A fetchland cracking, a Satyr Wayfinder dumping a forest, a creature with dredge picking up extra lands, a discard outlet pitching basics: any of these flips the Insect on, and the once-per-turn cap means you cannot chain three lands into three bugs in a single turn, which is what keeps the clock honest without dampening the engine across multiple turns. It rewards self-mill builds for filling the graveyard, not for the milling itself. The design sits at the intersection of two green obsessions that rarely shared a card cleanly before this: graveyard density and going wide with creature tokens. Where most token-makers ask you to pay mana per body, this asks you to play lands into your graveyard, a resource a dedicated mill or dredge shell generates as a byproduct of doing what it already wants to do. The mill on your own upkeep is the engine's pilot light: a slow, free, self-contained way to keep feeding lands into the bin even when no other enabler shows up, so the Insect line never goes fully dark.
