Art by Quinton HooverPart of a 4 cube cycle with some unified patterns:
The cubes roughly pair with the seasons and I try to bring them out appropriately. This is winter.

I was looking to develop some new synergies while still staying in the boundaries of the snow theme. Uses the Kaldheim themes as a base but I've deviated a lot since then. Trying to go for a power level of something like 2014 vintage cube, where you can expect the battlefield to look something like "Glen Elendra Archmage holding a sword."
Some of the more novel things in the cube include:

Militant Monks | Prowess

Fallen Angels | Lifegain

Dwarven Bloodboilers | Equipment

Advance Scouts | Landfall

Icy Manipulators | Twiddle+Assassin Control / Artifact Prison

Karplusan Giants | Blue Moon Control

Ice-Fangs | Flash Draw-Go

The Balduvian Horde | Aggro

Tarmogoyf Nest | Ponza land destruction

Deadly Insects | Recursive Sacrifice / Depths Combo
