Each Fungus creature gets +1/+1 for each spore counter on it. {B}{G}, Exile a Fungus card from a graveyard: Put a spore counter on each Fungus on the battlefield.

{T}, Sacrifice a green creature: Target land becomes a Forest. (This effect lasts indefinitely.)

At the beginning of your upkeep, sacrifice this enchantment unless you pay {G}. Whenever a player puts a Swamp onto the battlefield, this enchantment deals 3 damage to that player unless the player puts a -1/-1 counter on a creature they control.
