Ranni, Dark Moon Witch

Whenever you cast a noncreature/nonartifact spell for the first time on your turn, you may search your deck for an instant or sorcery of an equivalent mana cost and cast it for free.

Whenever you cast an instant or sorcery, your artifact creatures gain a +1/+1 counter.

“ I am the witch Ranni. I stole Death long ago, and search now for the dark path.”
