This deck is mad fun if you are looking for some competitive jank. I have an 82% winrate with this deck so far and boy the games are so fun.
The Main Combo:
You want to Messenger Hawk -> Replicator Engine. You want Crown of Possibilities down as well, or a Breeze Dancer (and more than 1 of either is best). Use this to just flood the board with units to kill and control your opponent.
You also would love to have a Chalice down as you can drop a replicator engine then immediately chalice it which is absolutely great. Once the keywords start flying you will have some crazy engines to do some fun things with, namely Destiny, Echo, Killer, Lifesteal, Charge, Unblockable. Dusk Raider has the added benefit of giving berserk which is quite nice (and helps you reel in the keywords you really want by checking one off the list).
Enablers:
-Chalice, Temple Scribe, Second Sight, and Dusk Raider all help you get to your combo pieces early. Auralian Merchant can help you get a chalice or a crown depending on your need which is great too.
Support:
-Derry is great in a chalice deck and is also pretty dang good in a crown deck. You can get him up to an 8/8 if you chalice twice then ability, and if you have keywords on top of that it's amazing. He's also good to pop aegis, see cards in your opponents hand, and disrupt strategy by making certain cards 1 more expensive which can make a difference (ie torch)
-Dissociate is great as it's a multi purpose card. It offers spell negation and pseudo attachment removal. This will help you get past any huge roadblocks but really only delays it, so Passage of Eons is your best friend in relic heavy decks.
-Equivocate is your removal for the deck, it's quite a good card imo. I think I might want some more removal in the market though I don't know what I would use. I also use Temple Standard to bounce cards back to the hand but again that is only a temporary solution. Equivocate gets rid of any and all buffs to the card while in some cases transforming the creature into something useless.
-Amber Acolyte helps thin the deck and gives you power draw. She also serves as a good chalice target or blocker.
-Auralian merchant is a merchant. Enough said.
-Lumen Defender is a good card to help save your skin by giving health and providing deadly on a chalice-able body. He is a good answer to some bigger threats and is very helpful to stabilize against aggro.
This deck is of course weak to Avigraft so I might sub out dissociate for disjunction, I will have to play test it more to see.
