Infected Fungus

When Infected Fungus enters the battlefield and
at the beginning of your upkeep, put a spore
counter on a target non-land permanent
you don't control.
For as long as you control Infected Fungus,
creatures with spore counters lose all
abilities and creature types and become 0/1 sporelings.
When Infected Fungus leaves the battlefield
remove all spore counters from all permanants.
