Fungal Epidemic

When Fungal Epidemic enters the battlefield,
target creature without Contagious, gains
Contagious. (Whenever this creature blocks or
becomes blocked by a creature, if that creature doesn't
have Contagious, it gains Contagious.)
Whenever a creature with Contagious dies, create
a 1/1 green Saproling create token for each spore counter on it.
{b}{g}: Put a spore counter on target creature.
