Sporogenesis

At the beginning of your upkeep, you may put a fungus counter on target nontoken creature. Whenever a creature with a fungus counter on it dies, create a 1/1 green Saproling creature token for each fungus counter on that creature. When this enchantment leaves the battlefield, remove all fungus counters from all

creatures.
