You’d think but right now the playable payoffs for snow are Coatl, the black sweeper, red Skred, and white’s On Thin Ice. Not really sure where to take such a deck yet. Maybe it will make more sense with the rest of the set.

That being said, the new rainbow fetchland does help out snow a decent bit, as well as the one-drop cantripping color fixer. I would imagine a snow deck would be primarily blue/green, and then touch the other colors as needed for splashing, which might be able to work?

That does look like what it would take. However, it couldn’t just be normal dual plus snow because it would invalidate everything else.
Really curious to see if anything shakes out.
