This is the record that I'll be updating with any card changes or upgrades.
This is a more casual blue deck than Niv-Mizzet but it still has some really solid tricks. Grave Pact sub-theme, a smattering of mill cards and ways to give Wrexial haste, and the extremely threatening Guiltfeeder seem to work out rather well.
Totally disagree on the Glaciers though. If I run out of basics that would mean I had 6-7 activations of Glaciers and a fetch or 2. If it lasts that long, awesome.
Chainer, Dementia Master is worth running given how much mill you have.
Also, where's Geth, Lord of the Vault?
