Intro

You like to draw cards? You like to trigger lots of abilities? You like to burn your opponents? Then Ive got the right deck for you. Draw lots of cards, trigger lots of abilities and burn your opponent. No Chandra required!

How the deck works

You try to draw a 2nd card each turn and trigger Irencrag Pyromancer and Improbable Alliance to build your advantage and overwhelm your opponent. The deck is very adaptive and provides lots of ways to quickly filter and find your key cards. Added burn spells provide a smooth experience.

The deck

4 Improbable Alliance - Key card. Produces 1/1 flying tokens. Also lets you filter your cards when in a top-deck contest with your opponent.

4 Irencrag Pyromancer - Key card. Burns everything. Your opponent will try to kill it with everything they've got, so protect it well.

4 Stormfist Crusader - The reason we splash black. Automatically draws a 2nd card each turn, which is exactly what we want. Furthermore we deal 1 damage to the enemy and can pressure 3CMC planeswalkers.

4 Opt - Simple draw and filter.

4 Thrill of Possibility - Filter your cards. Also draws two(!), which means you can easily trigger your Irencrag Pyromancer and Improbable Alliance during the enemys turn.

3 The Royal Scions - All three modes are relevant for us. Draw and filter your cards, buff your faeries and Stormfist Crusader and when left unchecked draw lots of cards and deal lots of damage.

1 Expansion // Explosion - Versatile draw tool and finisher. Also very nice to copy an opponent's GoodSpell(tm) or win a counterspell war.

2 Commence the Endgame - Another way to finish the game. Also draws two, same as Thrill of Possibility. This is also nice for defense because it cant be countered and provides a surprise blocker.

4 Bonecrusher Giant - Filler. Burn the opponent and advance the board.

3 Brazen Borrower - Filler. Bounce threats and provide another avenue of attack. Works surprsingly well and is very annoying. 

3 Shock - Filler. Burn and disrupt the enemy.

1 Castle Locthwain - Drawing a card when in dire need.

2 Castle Vantress - Filter your deck.

Sideboarding

3 Disdainful Stroke - Really ugly cards are usually 4+ CMC, so why not shut them down with a nice and fresh counterspell?

2 Flame Sweep - We need a little time to start our engine, and this provides a hot break.

2 Noxious Grasp - For when we cant deal with Questing Beast or Oko, Thief of Crowns.

2 Unmoored Ego - Remove the most annoying card from an opponents library.

1 Ionize - A more generic counter spell.

1 Chandra, Awakened Inferno - Another way to clear the board that cant be countered.

2 Lava Coil - More versatile burn that also exiles cards from the graveyard and can kill Questing Beast

1 Expansion // Explosion - A 2nd copy.

2 Latotep Plating - Protect your Irencrag Pyromancer from removal and yourself from discard.

Maybe

Sorcerous Spyglass - Deal with all the activated sacrifice abilitys (Witch's Oven) or planeswalkers.

Ashiok, Dream Render - Deal with annoying graveyard shenanigans or shut down searching your library (Golos, Field of the Dead)

Niv-Mizzet, Parun - Papa wants some action!
