Intro

My podmate bought me 3/4 of a deck as a gift, to see how I'd go with a storm deck as I've expressed interest in the concept and talked about the concept with him several times. He told me the next time I saw him for a game, to bring a bunch of Izzet staple cards without telling me the deck's strategy. I brought about 50 cards and enough basics, and this decklist was formed from the bones of the deck I constructed on the fly and played. I've tinkered with it a little, but there's still more to do.

Draw

Draw a card, maybe discard a card but you're playing from exile anyway? Not a problem. Notes I've discovered;

• Because your hand is usually empty, and the cards remain in exile until the next end step, playing interaction - counterspells in particulat - is hard. You need an instant speed draw, to hope you find a counterspell, and it's just no good. Better to play removal - chaos warp, resculpt, etc. - for after a problem hits the battlefield, than to try and kill it on the stack. Especially because you have no hidden information of what's in your hand, it's all in exile face up.
• Cards that say "as an additional cost to cast this spell, discard _ card(s)" are problematic if you have no cards in hand to discard. One or two of them are okay, but the current deck list has too many of those effects. Rummaging effects are fine, as long as it's not on cast is the problem. Cathartic Reunion in particular is a problem, and needs to go.

Storm

• The storm cards are pretty self explanatory. Cast lots of cards, get the most effects possible, play.
• Low land count is on purpose, might cut some high end cards and 2-3 more lands to keep the deck flowing and going. 23 sources of draw is almost ramp in effect - but 23 could be more!

Upgrades

• This deck needs Birgi and Storm Kiln Artist to keep the storm dreams alive.
• Be aware that as cards are exiled instead of being drawn with Eruth out, if a big card like Aetherflux Resorvoir gets exiled early, it's gone for the rest of the game. Very high variance in how the game goes, which will limit the power of the deck.
• The Combo-tastic area has no tutors. I just threw them in because, as per the intro, I was told I was getting an Izzet (Blue Red) deck with no idea what it did or needed. So a 2 card combo with no reliance on the rest of the deck felt like a useful include. They're going to go once something else goes in - though Thassa's Oracle might stay in, and combo with a Brain Freeze effect maybe?
