Erelia Ravencloud

Protection from artifacts, instants, and sorceries.
At the beginning of your upkeep, each opponent reveals the top card of their library.
Whenever Erelia Ravencloud attacks, scry 1, then uncover 2. (Reveal the top two cards of target
player's library. You may cast them for their casting
costs if they're noncreature spells, otherwise put them
on the bottom of its owner's library in any order.)
