Fungal Behemoth's power and toughness are each equal to the number of +1/+1 counters on creatures you control. Suspend X-[X][G][G]. X can't be 0. (Rather than cast this card from your hand, you may pay [X][G][G] and exile it with X time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.) Whenever a time counter is removed from Fungal Behemoth while it's exiled, you may put a +1/+1 counter on target creature.
