Stormshriek Feral

If an Omen spell has one or more targets and all of those targets are illegal when the spell tries to resolve, it won’t resolve. None of its effects will happen, and it will be put into its owner’s graveyard. It won’t be shuffled into its owner’s library.

If an Omen spell is countered or an effect causes it to otherwise leave the stack, it won’t be shuffled into its owner’s library.

If an effect instructs you to choose a card name, you may choose the alternative Omen name. Consider only the alternative characteristics to determine whether that is an appropriate name to choose.
