Mardu Burn (Modern)

Classic burn, just the Black splash that change.

I played a lot Nacatl Burn (Naya), and I had troubles against deck using big creatures, Gurmag Angler, Goyfs and Rhinos.

I was thinking on how to get rid of them, how to manage these cards :

• Roast ? No damages to our opponent, but hits almost everything (standard Goyfs is 4/5)
• Path to Exile ? When you want to race, you don't want your opponent to have an early land. On the other hand, I play the card against Bloom Titan, also Junk and Abzan Company.
• Pumping creatures ? With spells like Become Immense, Mutagenic Growth ? It's good, sometime, that's gave me some win turn 3 or get rid of */5 creatures but sometime it's just so bad. U'd like to see a burn spell instead of this.

Then I thought on splashing Black, instead of Green. I lose Wild Nacatl, Atarka's Command and Destructive Revelry.
So what do we have with Black ?

• Bump in the night : 1 for 3, it's like a Lava Spike with a Flashback !
• Crackling Doom : sacrifice the biggest creature you have and take 2, sold !

Post side we have :

• Lingering souls : awsome against control deck and Infect
• I don't have the card at the moment, that's why it isn't in the sideboard, but I'd like to add Deathmark, for Goyfs / Rhino haters, there we go ! I'd cut off Lightning Helix or Thoughtseize for them.
• I dunno about Thoughtseize, I guess it's not bad, getting their creatures removal or just discard a Kitchen Finks / Voice of Ressurgence / Geist, will try this one ! Btw, I just dunno which card will be cut to play them.

I don't have the Eidolons, that's why there is Hellspark Elemental, but Eidolon are way better for that spot !

Also, the mana base can be reworked, if you have Clifftop Retreat and Arid Mesa.

Update 08/29/2015 :

• Adding one Exquisite Firecraft
• Reworked the sideboard (there is some Lantern deck in my local meta, I need Artefact hates)
• Dismember, while I don't have the Deathmark

Feedbacks are welcome :)
