Sporogenesis

The most subversive thing here is the targeting clause: this enchantment seeds fungus counters onto any nontoken creature, yours or your opponent's, and the death-trigger that turns those counters into Saprolings fires no matter who controlled the creature. The card is a parasite, not a build-around payoff. You spend your upkeeps planting counters on the board's best blockers and attackers, then collect the harvest when removal, combat, or your own sacrifice effects clear them. A creature with three counters dies into three Saprolings, so the longer the enchantment sits, the larger each payout grows. The leaves-the-battlefield clause that strips every counter is the discipline holding the engine together: the fungus counters are leased, not owned, and an opponent who answers Sporogenesis erases the latent token bank before it can cash out. That tension defines the card. You want to accumulate counters slowly for a bigger eventual swing, but every turn the enchantment stays on the table is a turn it can be destroyed and take the whole stockpile with it. It belongs to a strand of Saproling design that runs through the Fungus and Thallid lineage, where bodies are currency and patience is the cost. The counter-on-anything reach is what separates it: rather than growing its own tokens the way Thallids did, it monetizes the death of creatures it never had to cast.
