2 rulings from Wizards of the Coast
- 1 May 2007Your other creatures that produce spore counters (such as Thallids) can create a Saproling by removing two spore counters (by using this ability) or by removing three spore counters (by using their own ability).
- 1 May 2007All creatures you control gain the ability, regardless of whether they have spore counters on them, which means for example, they would lose the bonus from Muraganda Petroglyphs.
