Elusive Grevena

Bestow {2}{b/g} (If you cast this card for its bestow cost,
it's an Aura spell with enchant creature. It becomes a creature again if it's not attached to a creature.)
Whenever Elusive Grevena or enchanted creature
would gain a spore counter, it gains that amount
of spore counters plus one.
"They hide far beneath the earth, in caverns of glittering insects where we are not welcome"
