Plan to swap in Auric Interrogator for Reliquary Raider and Champion of Cunning for Rindra, the Duskblade to test if it can play better with big creatures. Reason for omitting Auric Interrogator initially was that it was only reliable if pumped by Katra, the Devoted. Swapping in the Champion of Cunning gives it two avenues of additional +attack.
The biggest issue with the deck has been getting the proper influence to play my hand so I swapped in Favor cards to help in that regard. So far everything has been going rather well. Plenty of removal, card draw, and sustain to win matches. Still needs further testing on the ladder.
The removal is all single target and relies on Black-Sky Harbinger to pop aegis and remove small threats. If you find that board clear becomes an issue, you should be able to add either Lightning Storm or Hailstorm in exchange for the Suffocate More to come at a later date.
