The Original Idea

This has been my Modern pet project for more than five years. I wanted the original iteration to be good, but it never panned out that way. Mostly due to the high mana cost of a few Coldsnap cards, specifically Rimescale Dragon and Rimefeather Owl. I would combo them with Tamiyo, the Moon Sage for a large card draw in her second ability. As you call tell, there are none of those cards in the deck now. It seemed appropriate to update the with the addition of Damping Sphere from DOM. I find it has more utility than Blood Moon because it allows me to still operate my non-basic lands, even though it has been a staple in Modern for as long as I can remember.

I'm sure the first thing you will notice is the use of Snow-Covered and Snow lands. You're thinking "why?" right now, aren't you? As stated in the last paragraph I was trying to find a way to make use of snow permanents in a Modern build. Ultimately I only have two cards that truly take advantage of the snow-covered lands; Scrying Sheets and Skred. With Modern Horizons I hope I'll have more snow permanents that I can actively use in this deck.

The Combo (Feature Cards)

You can theoretically win by turn four if you draw the needed cards from your opening hand. At least three land cards, perferably one Island, one Mountain and any other land. Training Grounds, Izzet Guildmage, Soulbright Flamekin and Manamorphose for your other four cards.

• Turn One: Play an Island, tap to play Training Grounds.
• Turn Two: Play Mountain/Sulfur Falls, tap Island and Mountain/Sulfur Falls to play Soulbright Flamekin or Izzet Guildmage.
• Turn Three: Play Island/Mountain/Sulfur Falls/Scrying Sheets, tap Island and Mountain/Sulfur Falls to play Soulbright Flamekin or Izzet Guildmage.
• Turn Four: Tap one land to activate Soulbright Flamekin's ability to target itself or Izzet Guildmage and have it resolve, repeat this process two more times. Once it resolves a third time you will have eight red mana to cast Manamorphose for two red mana of the eight to add one red, one blue mana using one blue mana to activate Izzet Guildmage's instant ability to replicate Manamorphose as many times as you need to dig for a win-con.

NOTE: Soulbright Flamekin isn't completely necessary here, it does however give us a mana fix if we manage to draw sorceries out of our draw steps.

The Spice (Lands)

The Win-Cons (Support Cards)

• Even though Boros Reckoner dies to being targetted by Skred (If you have enough snow permanents out.) That damage is redirected to our opponent.
• Lava Spike with Izzet Guildmage is the true win-con. It's a pseudo-storm mechanic.

The Other Stuff (Utility Cards)

• Cryptic Command will mostly be used for sounterspell and card draw.
• There are better counterspells than Dissolve, but the scry is a helpful filter.
• Keranos, God of Storms can give us an extra card draw or a free bolt.
• Remand has card draw and is an early answer if you don't have the other two counterspells.
• Serum Visions is for card draw and filter.

Hate on the Meta (Sideboard)

• Cyclonic Rift is just a catch all.
• Damping Sphere is for Tron.
• Lightning Bolt and Mizzium Mortars are for creature heavy and tokens.
• Shattering Spree and Vandalblast are our artifact hate suite.
