Emissary of Eldewyn

Flash
When Emissary of Eldewyn enters the battlefield,
look at the top four cards of your library, exile an instant or sorcery card from among them. You
may cast that card from your exile without
paying its mana cost until end of turn if it has a converted mana cost 3 or less.
Those who follow Eldewyn's ideals follow the idea
that all can be perfected.
