Hell yeah, +1 from me looks super fun! Elbrus, the Binding Blade  ^Flip and Westvale Abbey  ^Flip are such rad flavor wins! Even if they do take a bit of work. Magus of the Moat is a great idea, using that along with Ghostly Prison, Norn's Annex and the like to make a pillow fort sub-theme would be an interesting direction! Super cool!

With everything everywhere, it was hard to tell how many ways you have to protect Kaalia. I have a Kaalia deck myself, without Demons, and Kaalia still turns into "4 mana, discard a removal spell." My personal advice, run Dragon Tempest to get the attack trigger ASAP. Another add is Skithiryx, the Blight Dragon. I just love infect.

Great deck, my guy!

Have you considered Land Tax as a way to fix your mana early on and make sure you consistently hit your land drops for turn? Rune-Scarred Demon is an additional tutor you could play for free given Kaalia's ability.

I love Rune-Scarred Demon, it's already in my deck! Dropping it with Kaalia is always a nice feeling.

I'd looked at Land Tax but unfortunately I just don't run enough basic lands to make it worth it. Part of why I was looking at Weathered Wayfarer is that it's not limited to basic lands. My mana seems to be fairly stable, fingers crossed.

Ah my bad, i should have checked the quantity of basics you had. I kind of forgot it only grabbed basics, I'll be honest. I did look for the demon, but i only checked in your lists of angels, demons, and dragons. Haha. Didn't check the tutor section. My bad!
