Featherskin Boa

Play with the top card of your library revealed.
Whenever you cast a spell for the first time
each turn, if the top card of your library is a
noncreature nonland card, you may cast that
card as though it had flash this turn.

"The feathered snakes live deep in the jungle, and rather than use venom and coil, they hex their prey, stunning even the strongest mind with subtle magic."
