Apothecary Gary, "Symbiont"
Legendary Creature — Fungus Insect
Apothecary Gary enters the battlefield with two spore counters on it.
You may tap untapped creatures with one spore counter on them to add {g}, and with two or more spore counters to have it deal damage equal to it's power to any target.
When a creature with a spore counter on it deals damage to another creature, put a spore counter on each that have less than two.
1/1
"You control creatures with spore counters on them.
T: Put a spore counter on target non-artifact creature. It gains 't: add G', and 'when this creature is dealt damage, remove all spore counters from it', and is a fungus in addition to its other types."
just to make wording a little cleaner.
