This is the first Elysian deck that's been fun for me to play in ages. The Insignia makes the Dawnwalker influence trivial to get and Preyfinder is a great addition to the Elysian Killers archetype. The early game can be quite weak that's why Hailstorm is needed in the Market. I also tried Gnash in the main deck but he's been better in the market as it's a win more card when the summon doesn't matter.
I had some of the sweetest chains of drawing cards with this deck (even without Preyfinder) which makes it super fun to play.
