Interesting deck! I would consolidate a bit. Instead of running 1x of a bunch of different relics, pick half of them you like the most and run 2x (assuming you have 2x).
There are also creatures (like Leviathan Hunter) that give you relics. They don't do much on their own but are great with Avalanche Strike and Carnage Sweep.
Thanks for the suggestion!
Forgot to mention this is a F2P deck. That's why its a bunch of different relics and that's all I have. Lol! Otherwise, I would have run 2x each. Unfortunately, I also don't have Leviathan Hunter (that's a genesis card!)
