Daggstorxal the Blighted

Flying, hexproof
When Daggstorxal enters the battlefield, exile cards from the top of your library until you exile three instant and/or sorcery cards, then put the rest on the bottom of your library in any order.
Whenever you cast an instant or sorcery spell, copy each instant and sorcery card exiled with Daggstorxal, then cast the copies without paying their mana costs. If those spells have targets, targets are chosen at random.
