A solid deck, adding ToF cards looks interesting. I thought about Strength Stealing Control Deception but then discovered that aggro Strength Stealers work well too.
This WR was success (unlike the previous one), starting in Auric and ending on Ethereal. Some luck also was on my side. The last version:
Deck code: GU_1_2_CCmCCmCCQCCQCFVIAlIAlCDDCDDIClIClCEPCEPKDSKDSBHMKCZKCZKCbKCbKCgKCgCEVCEVIAkIAkCEcCEcCAbKCu
Selfless Guildmate can win the game when you have a Sanctum card allowing you to choose a card from your deck, the Trial Begins.
Lokian stops relics (great vs War).
It looks very interesting!
