I'd take out Pyxis of Pandemonium as it does nothing for devotion and I don't think the ability is that great. I'd also take out the Diabolic Tutor out of the side board because it seems slow. I'm iffy on the Strionic Resonator but I can see how it is good. I'd probably push for some Mutavault as that has great synergy with Pack Rat Also personally I'd main deck more removal. I'd possibly add more Crypt Ghast so you could have something. I'm not entirely sure. I'd definitely add Underworld Connections or Read the Bones probably Underworld Connections as your Merchants route for business. It's Pack Rat fuel and can help late game. More extort is also an option with say Thrull Parasite as a cheap one drop but, that's iffy. However it does help going into devotion sometimes. Overall though I like the deck with a bit iffy on some cards but really not bad. Maybe your current draw power is enough.

Don't knock Pyxis of Pandemonium until you've tried it. It's really easy to finish the game by cracking Pyxis, with the right setup. And Strionic Resonator , as you said, is good. Diabolic tutor is mostly to search up exactly the card I need when I need it, ut since the card I need is usually Pyxis, maybe I should just side three more Pyxis instead... I can't afford more than one mutavault, should I put in just one? Thrull parasite... could be a thing, I guess. Thanks for the feedback!

Ok, I realize this deck doesn't look that impressive when you haven't seen it in action, but COME ON GUYS. I have literally never lost more than one game in a row with this deck. That's gotta mean something.

Sanguine Blood isn't terrible, but compare it to Nightveil Specter and you can see that the Specter can give you A) More devotion, B) More value faster. I can see why Blood is in there, but I just think the Specter could give you more value. +1 for originality though!

Thanks for the +1! I know Sanguine Bond isn't the strongest card available, but I wanted a deck I could use it in... so I made this. Sanguine Bond is almost never relevant, but neither is Nightveil Specter , so... I don't know. But Thanks!

I'd love to play this against my Jund deck sometime- seem very interesting, especially with the Resonator. I'd be curious to see what the Pyxis does, too.
