may i suggest Braid of Fire?

Braid of Fire is not all that great, since I have only access to that mana during my upkeep and I have few big damage dealing spells at instant speed. But it's fun.
I will add it to maybeboard

Thanks :)

Edit: Also It's expensive!

Young Pyromancer??? It's even got Chandra on the art!

That's not Chandra....

Young Pyromancer didn't make the cut because it does too little and is too squishy for EDH.

Thanks for your thoughts though :)

Since you are running Repercussion I would recommend Satyr Firedancer. And although it is a bit expensive, Boseiju, Who Shelters All is worth it to make your spell uncounterable.

So random recommendations: Red Sun's Zenith, some phoenixes since they can be reobtained after they hit the graveyard like Shivan Phoenix and they're all pretty cheap, Guttersnipe, Fork + Increasing Vengeance to copy your spells for more damage, same with Reverberate except you can also use it to copy enemy counter spells to help your spells go through, Spawn of Thraxes for all that lovely bonus damage from your mountains, and Thespian's Stage to make a copy of your Valakut, the Molten Pinnacle for double damage! Oh, and an Expedition Map to grab your valakut or thespian.

First off Guttersnipe does too little, I simply don't cast enough instants or sorceries to make him worth it. Phoenixes also do too little, people always want me to add them but I don't see the point, what should I do with them? use them as repeatable chump blockers? they are too expensive for that and too weak to be of any other use...

Satyr Firedancer didn't make the cut simply because there were better cards than him to add. Fork simply costs too much money for what it does.

I've been trying to find a place for Increasing Vengeance + Reverberate but I don't know what to cut (maybe someone can help with that?).

I usually don't have enough mountains in play to make Spawn of Thraxes worth it (on average 8-10 mountains at the end of the game) which is also why I dont want to use slots for cards like Expedition Map, I play Valakut, the Molten Pinnacle because it's fun, but it actually doesn't contribute much.

Since copying stuff is fun though I will add a Thespian's Stage

Thank you for your thoughts on this :)

Shrine of Burning Rage? Ruination, because you're running mostly on mountains. And Pyroclasm probably as a sideboard option against token hijinks, but I had to suggest it because that is my favorite Chandra quote ever.

Thanks for your comment :)

Shrine of Burning Rage is a bit too slow for me, it takes too long to build up the charge counters and the more counters are on it the more hostile the other players will become. this deck doesn't take hostility well...

I won't add Ruination because nonbasics aren't that big in my playgroup and it would be a dead card sometimes.

I already run some cards like Pyroclasm so I don't really need it...

I love everything about this deck---especially Red and Chandra.

I would seriously reconsider putting Furnace of Rath back in. The whole point of the furnace is that you only play it when you can deal enough damage to fatally incinerate your enemies. Otherwise, keep it in your hand. (Though that wouldn't be a very Chandra-like thing to do.)

Mana Flare is a great way to increase your mana production.

Copy spells like Reverberate, Reiterate, and Fork are perfect for giving you extra mileage with your burn.

Rolling Thunder is a good, solid X burn spell.

Jaya Ballard, Task Mage must be in this deck. Chandra has even said she wants to meet her.

Recoup and Past in Flames. Past in Flames not only works excellently with burn---it even thematically fits Chandra's backstory.

I also suggest Scour from Existence. It is highly likely you will meet some indestructible shenanigans, and red is sorely lacking exile removal.

If you're having problems cutting cards, I would suggest lands. I know the general EDH deck construction philosophy is 36 lands, but you're a mono-colored deck and don't run green. If you draw a land full of hands, you have no way of playing everything. It's likely that later on you will be stuck drawing lands. In my non-green decks (which is most of them; I don't particularly enjoy the color), I tend to lower the land count to 33 or even 32 if there is a lot of artifact ramp. You can try if that works for you.

Oh yes: Urza's Rage.

I updated my deck, since I haven't done that for a while.

Rolling Thunder is already in.

I already have enough damage increasing cards in my deck so Furnace of Rath won't go back in. [mana flare] usually helps my opponents more than it helps me, so no. I believe I have enough copy effects in this deck already, same goes for flashback, flashback also makes the spells cost much more to cast so it isn't very efficient.

Jaya Ballard, Task Mage is only good if you play cards that synergize with her and I don't play those, also while she may fit flavourfully, she doesn't really fit in here otherwise.

Urza's Rage is just a worse and less flexible Banefire there are lots of cards that are better than this.

I've thought long and hard about adding Scour from Existence, but I decided not to add it. I need my lands too much to cut any of them, the only other card I could have cut for it was Unstable Obelisk, but the obelisk is just more flexible. I guess if I'm confronted with a indestructible shenanigan, I'll just have to defeat it's controller before he gets to use it.

Still I thank you very much for your thoghts on this :)

Hehe, I've been trying to get burn to work in EDH a lot, so I was just sharing how I was able to get mine to work. Just yesterday I dropped a triple-copied, kicked Urza's Rage on someone, then Comet Stormed for 31 right after. Before that I used a copied Volcanic Offering to burn four creatures a greedy Karador player had; my Vicious Shadows killed him when his four guys died. In any case, have fun with the deck! I just love it when underdog strategies work in EDH. It's so much more epic in a format that people like playing infinite combos in. May the ashes of your enemies rain down softly upon the blasted landscapes of your battlefields!

Glad you like it :)

I love this. I play a Ben-Ben, Akki Hermit deck, so I'm all for fun mono red. That being said, I looked through the comments and came up with a few suggestions

Red Sun's Zenith I know it was mentioned before, but I think it deserves a second look. Having a spell that you can keep using is really good, though I understand that it's a bit of a non-bo with Charmbreaker Devils

Since you're using effects that limit attackers (wonderfully may I add) I would consider Silent Arbiter or Caverns of Despair woo Enchant World!

Planar Portal is a good tutor in any red, since you'll have a ton of mana

Staff of Nin / Ensnaring Bridge are good artifacts for red, depending on how small your hand gets

Chaos Warp - Solid all around removal

Planeswalker's Fury is on theme for Chandra, and repeatable damage.

I hope this helps!

Thank you for your comment.

Red Sun's Zenith: I believe I have enough of these "deal X to target creature or player"-spells in here and most of them are more flexible than this. the only one thats similar is Devil's Play and if I have to decide between being able to cast again from the graveyard and maybe sometime drawing it again I will choose former.

Silent Arbiter: Is a creature, which means I will not be able to play some of my burn spells if he is my only defense.

Caverns of Despair: Interesting, sadly it's not excactly cheap and for what it does its not a price I'm willing to pay

Planar Portal: I'm willing to add it, but I wonder if it would be worth it. I meand I could search my deck for ramp or something defensive, but those things usually come naturally and paying 6 to search for a burn spell? I don't know.

Staff of Nin: Too little card draw, it always feels very unstatisfying. And the "tap to deal 1" is pretty much useless.

Ensnaring Bridge: Would have added it long ago, if it wasn't so damn expensive...

Planar Portal: In my opinion not a red card, so I'm not playing it.

Planeswalker's Fury: funny card, but a bit too unreliable. paying 4 to deal 0 feels pretty bad....

Thanks again for your thoughts

While I have zero experience with commander, I do like Chandra as well and have a little experience with burn and red cards. Noticing that Incinerate and Chandra's Phoenix aren't in there. Not sure how they would fit for commander, but both would fit the Chandra theme. The Incinerate is from the duel decks: Jace vs. Chandra.

Thank you for commenting :)

Sadly both Incinerate and Chandra's Phoenix aren't very good in EDH

Nice to see Increasing Vengeance made the cut, I think you really need to cut some of those artifacts because the quantity you have is really high for a burn deck... But you should put Ruby Medallion and a Hellkite Tyrant if you're going to to continue being this artifact heavy for an alternate wincon

Young Pyromancer and Guttersnipe are solid

+1 for mono-red!

Magebane Armor: not red, but it keeps Chandra (or one of your other creatures alive long enough :) (that, or Sword of Fire and Ice...but that is really $$$ )

well red by itself just doesn't have the efficient ramp, card draw and especially protection this deck needs, but it has never made any problems for me to be this artifact heavy.

Ruby Medallion is more useful when you play many small spells instead of few big ones like here, so it's not good enough.

I have a feeling that Hellkite Tyrant would be a wincon only sometimes, first of all I never have that many artifacts out, maybe six at most, since this deck lacks card draw and matches with it usually don't go that long (either because I get killed early, which doesn't happen very often, or because I kill everyone else pretty early in game, which happens more often than you might think), second artifacts aren't played very much in my playgroup.

It is my believe that, at least for now, burn in EDH is only possible in artifact heavy decks. This may be a weakness, but it's not like this deck can't do anything without artifacts.

Thank you for your thoughts on this.And thank you for getting me to think about this :)

Young Pyromancer and Guttersnipe have the same issue as Ruby Medallion. I had them in during the early drafts, but I don't cast enough spells to make them worth it.

As for Magebane Armor this could be useful, but I believe I play too few creatures for it be good and I don't really need it for my commander, I will be able to flip her, in most cases, before she dies. The same goes for Sword of Fire and Ice, that would even be a bit of a waste since I would almost never be able to use it's primary effect.

I thank you both for your input :)

Wow, I see a lot of missing burn spells; Lightning Strike, Lightning Bolt, Shock, Exquisite Firecraft, Worldfire, and Searing Blood are not here.

Creatures; Monastery Swiftspear, Guttersnipe, and Young Pyromancer. Two creatures that help burn.

Lands, any mono color deck can use Nykthos, Shrine to Nyx. It is useful to help you mana pool.

Few more things,

Elixir of Immortality over Cranial Archive?

The Chain Veil to help quick ultimate Chandras',

I was thinking Tormod's Crypt for the sideboard, but that's your call.

All those burn spells are quite bad in EDH and Worldfire is banned. I already wrote why Guttersnipe and Young Pyromancer aren't good in this deck, pretty much the same goes for Monastery Swiftspear just that she generally isn't very good in EDH.

I decided against Nykthos because I don't play enough red permanents to even reach a halfway decent devotion count.

The Chain Veil wouldn't pull it's own weight in this deck and I chose Cranial Archive because I can also use it as graveyard removal and it lets me draw a card.

Ok. It seems like you got this figured out.
