Currently on a 15 game win streak with this deck on ranked. I've been testing different builds of Aurelian pretty extensively these past couple of days and this is probably my most optimized build. I really like these colors and I think display of knowledge is absolutely insane.
Maindeck Card choices
--------------------------------------
Display of Knowledge is one of the main reasons why we play
Ayan, the Abductor because killing
Howling Peaks is really important and being able to flash Ayan in and buff him can really mess up your opponents day. I also love playing the relics in the deck.
Eye of Winter is great in topdeck wars against all creature based decks and being able to hit
Azindel's Gift against control decks every game with display absolutely demolishes them
Only 3x Merchant - We don't really want to draw more than one merchant each game because all the cards in our market are either redundant effects or end the game, making multiple merchants worse (and its very easy to hit your first merchant with 4x
Strategize and 4x
Wisdom of the Elders)
Jennev Merchant over
Great Valley Smuggler - The Black market is much worse in this deck. The bigger body (surviving hailstorm) is nice and lack of anti-synergy with Vara is great too, but Hailstorm and Display of Knowledge have been very good for me and are too good to pass up. If you're facing lots of relic removal I'd switch to smuggler for
Disjunction and put the 4th
Display of Knowledge back in the main.
2x
Lightning Strike - This is for weapon destruction and beating early multi color aggro decks over
Annihilate
3x Seek power - With all of our draw spells and 4x
Auralian Cargo, seek power is pretty redundant and our powerbase is already fine.
Not playing the 4th
Banish - Banish is versatile and strong but we already have tons of removal and most of the strongest relics cost more than 4. If you're facing lots of
Avigraft shutting off your Varas or Ayans definitely put that 4th in.
Market
------------------------
Permafrost - Cheap removal for early game or when trying to push through damage. I've tried a feeding time in this spot but it doesn't work as well because perma allows us to play it and other cards in the same turn.
Hailstorm - This slot is teched for ladder and as I've been facing loads of aggro decks I've found it pretty important. If you aren't facing as much aggro I'd recommend swapping the copies in the main deck before this copy in the market
Display of Knowledge - This card is so important that having the 4th in the market is necessary. Every mode is amazing in this deck and this card is what you should take when you're just playing your merchant for tempo because this card is so versatile and useful at every state in the game (unless you have both relics)
Brilliant Idea - Huge refill. This card is very strong but I'm really not sold on it. Mostly just insurance against control. Rain of Frogs is equally good in this slot but I just love drawing cards
Scourge of Frosthome - Game ender against control and when you need a big butt lategame against aggro
All in all, looks like a more vulnerable Feln control from the old days. But I could be completely mistaken.
