Standard burn Izzet deck I made.

Staples(almost never removed):

4x Young Pyromancer - Wins games all the time, great against deso demon which shuts down my deck pretty hard, good against devour flesh etc. just a good card with this deck. He's also easy to protect because against control I can get him out as early as turn 3 with a mizzium skin.

3x Guttersnipe - The reason I don't run 4 is because, as awesome as he is, he oftentimes can't be protected since he essentially costs 4 mana with a Mizzium Skin or Dispel or 5 with an Izzet Charm or Negate. Anyway, if I can protect him or even get two out at once he essentially wins the game,

4x Turn / Burn - Turn is amazing, takes out thassa, takes out desecration demon, takes out all those big green creatures, and burn is just icing on the cake.

4x Lightning Strike - yup, it does work.

4x Magma Jet - Just an amazing card, 2 damage and 2 scry??? Never not want to run this.

3x Spellheart Chimera - Dies to everything short of Magma Jet, no protection in hand and this card means a dead card. However, he's a wonderful win condition, and can swing for around 7-8 damage mid-late to lategame. Quicken also has fantastic synergy with this card.

Non-Staples(I will sideboard these out at times)

3x.Izzet Charm - Izzet Charm is apparently THE best charm, however I don't feel this is the case in standard and I really am considering splashing white just to get Boros Charm. However, this card is still pretty good, it can stop planeswalkers, get instants and sorceries into the graveyard or chandras in the graveyard if i want to keep other cards, and burn creatures. It's a dead card vs control though and decks with big creatures, which is HUGE at my LGS which is why I don't love it like most people do... so I side this out often.

4x Mizzium Skin - The only time I will side this out is if my opponent has very little to no removal at all. It seems like an awful card, but letting a young pyromancer/spellheart/guttersnipe live for even one more turn can mean the game, and for guttersnipe and pyromancer you're getting a free token or 2 damage off of it. However, it can be a deadish card.

4x Chandra's Phoenix - I brought this in because of a suggestion, then brought it out because it got sideboarded HARDDDD when I went 0-4 at an FNM. The card's good but between Skylasher , Scavenging Ooze, Desecration Demon, Nightveil Specter, and other cards.... it gets countered pretty hard. However, game 1 against a non-mono devotion player it puts in some goddamn work. Great card, and it's nice to have a creature that DOESN'T depend on me protecting it.

4x Quicken - Seems like a weird choice, but it triggers pyromancer and guttersnipe, and makes my deck 54 cards. I tried running Divinations for card draw instead, but hated it. I might replace these with Steam Augurys though... who knows.

Why I think I lost at FNM/a tournament

My first tournament 2-2 - Yup, my very first time playing in real life was at a tournament. I was incredibly nervous and made a ton of misplays, including mizzium mortaring as an instant and countering uncounterable cards, sometimes "getting away with it". Walked away from this feeling kinda bad... but happy that I finally got some real experience with my deck. I don't quiiiite remember what the build was at the time, but I remember it had 4 shocks, 4 Steam Augurys, 1 Ral Zarek, 2 Counterflux and no Mizzium Skin / Quicken / Chandra's Phoenix. It had 4x guttersnipe, 4x izzetcharm, and 4x spellheart as well.

I did OK, but the main reason I didn't just go 0-4 was because I really "cheated" this one game vs a Golgari player, he used Abrupt Decay on guttersnipe I think and I Counterflux ed it. However, it COULD NOT be countered which he realized later, which was actually very bad. The other person I beat was playing this maverick blue white enchantment deck, who I crushed really hard... I guess that was an OK win.

My first FNM Yup, I went 0-4. Very discouraging. I was really bummed too, because I thought I actually improved my deck. This deck was essentially the same as the one you see now, except 4 Shock instead of mizzium skin i think?? No quickens too... I forgot what I had instead. I had basically zero card draw, used all my burn on creatures and then my opponent drew a big creature like a deso demon and crushed me. My Chandra's also got sideboarded really hard too.

The main reason I lost I think is my sideboard was so damn weak when I went. I had basically just random ass cards in there, like 3 gainsays and then I never played a monoblue player lol... Also I ALWAYS went 1-2 in every game, winning the first one decisively and then after sideboarding losing the next 2 games. So I definitely think my sideboard was the problem.

My second FNM 2-2 but i still went away very discouraged. This deck is essentially the one I was playing except I think... I took out the chandra's, and had only 1 [Quicken]] and 3Divinations as well as 2 Ral Zareks. I only won against a new player who is my friend, and some other guy whose deck wasn't even complete. Meh. It taught me I don't need card draw THAT bad and to bring back the chandras.
