ThisIsBullshit but it isn't rainbow anymore. And thanks!

I would suggest Boros over Mardu. The reason being damage to ourselves. Anyone who played Cruise Burn knows how much damage you take from fetching for three colors. In that build it was ok because one Treasure Cruise wins you the game 90% of the time. In Mardu, Bump in the Night is usually not going to be resolved for the win.

Grim Lavamancer as a three of is what you replace cruise with. Card advantage is what we lost with the bannings, so getting it back is where the deck needs to go. Cruise and Mancer share the property of using the graveyard, which means they benefit from the same things. Instead of bump, you run Shard Volley as a resource enhancer and flood insurance.

ConBurnMadMan, I actually don't really like Grim Lavamancer. I find it just tends to eat a bolt. IF anything, I'd recommend to keep it mardu and bump Searing blaze up 2.

The reason we splash black is that Bump in the Night is a bolt that's just flat out better than Shard Volley. Plus, you have to think of our match ups we're likely to face.

1) Abzan/Jund2) Twin3) Affinity 4) Zoo

We can keep aggressively playing burn spells to kill Twin as the current builds are going to be too slow to keep up, and we can very easily punish Abzan and Jund's use of cards like Dark Confidant.

We have to try to race Affinity and force a t4 kill, which in itself can be hard,

Zoo is the match you want Searing Blaze the most in, so you can play a land, kill a Wild Nacatl, a Kird Ape, or a Tarmogoyf

It comes down to "Do you want to splash an extra color, and take damage from shocks" or "Do you want to rely on a creature that catches a bolt quick"

@bamfbanki Jund/Junk is almost an auto win with what ever build you play. Zoo I agree Searing Blaze is an all-star in, but Bump in the Night is not a good card in that matchup. It's sorcery speed and can't hit a creature, Shard Volley is instant and can kill their win cons. The flashback is also almost always irrelevant. Affinity is where you are way off. We are the control deck in that matchup. We dont race, we outclass their cards with cards like Destructive Revelry, Searing Blood, Searing Blaze, and Smash to Smithereens. You control their drops and win with timed burn. Also, Grim Lavamancer is an all-star in that matchup, he kills most everything they drop.

Grim Lavamancer was the card we dropped to put Treasure Cruise in the deck. It was just better card advantage. I think more people would understand him if he read a bit differently.

Lets imagine he text was, "During your upkeep draw Shock. Grim Lavamancer can't attack if you cast shock."

Everyone would argue how he is the best Burn creature ever. I'm not saying he is the best, that honor still lies with Goblin Guide, but people would still say it. It's the reason you run Eidolon of the Great Revel in burn. Virtual card advantage in the form of 2 damage burn spells.

The meta is going to be much like it was pre-Khans, except we are a better deck because of Monastery Swiftspear. Take a look at the top 8 of the last GP before Khans. You'll find two Burn decks there, one of which placed first. You'll notice both are Boros, and the winning deck list is running 3 Grim Lavamancers.

Having a bunch of bolts is awesome, but top decking a fetch a being able to win off of it because it gave your Grim Lavamancer enough fuel to go to the face is much better. Card advantage is what Magic is all about, card advantage that does damage is what Burn is all about.

Tarmogoyf is a $200 card that eats removal most of the time he is cast. So why do so many people play him?? Because when he sticks he wins games. Samething Grim Lavamancer does for our deck.

Grim Lavamancer is fantastic. I used to run three and would draw at the wrong times. Bump is fantastic. Plus two color is boring, four color is where it's at.

Winning is never boring ;)

The thing is, I do win, a lot more than my friend who plays a identical list minus black, with shard volleys.

I run a full set of both. I can usually overkill on turn 4, occasionally turn 3. I just bought a lavamancer last week, wondering if I should drop a card for him as a one-of.

ConBurnMadMan You'd be surprised how much work Bump in the Night can do. It's another Lava Spike, which is very powerful, and isn't red so it isn't affected by Dragon's Claw or the like.

The flashback can be relevant if you're having a flooded game, which can happen, and it gives you some assurance that if you get to 6 lands then the Bump in your graveyard can kill them. Once I was even at 7 lands and Bump into flashbacked Bump for the win. It's very uncommon, but it happens.

I spent a long time running Shard Volley, and my biggest problem was it can't be cast in multiples and can't be cast before it's lethal. Bump can do both of those things. There is nothing worse than having one land and two Shard Volleys in hand. In my experience Shard Volley has cost me games where it wouldn't have if it was Bump in the Night.

I agree with your evaluation of Grim Lavamancer. I've been trying to tell people this all year! Having multiple is pretty bad, but getting out one on turn 2 or 3 against Aggro or Control is great. He's in my deck, Lightning Bolt and Some Lookalikes, as a 2-of.

My friends are getting into modern as well. One's playing Zoo, the other is playing Affinity. As such, I modified my sideboard, dropping the Soulfire Grand Masters for 2 Stony Silence, although I am considering Kataki, War's Wage instead. What do you think about it?

If I had to throw in my two cents, Kataki looks okay on paper. Myself, When I see an affinity matchup my response is generally to side out my bumps and another playset to side in 2 Rakdos Charm, 4 Destructive Revelry and 2 Anger of the Gods.

I do exactly what yamishi said.

You should make the featured card The Cheese Stands Alone

Why not Volcanic Fallout instead of AoG? Fallout hits players along with the pesky creatures and hits players. I think the damage to players makes up for only dealing 2 damage to creatures. Also, I see what you're thinking with Mutagenic growth but I don't think it's worth it. What if you top deck that turn 4 with an empty hand and no creatures on board? Personally, I think that the higher CMC of Flames of the Blood Hand is worth the topdeck burn and the anti-lifegain effect.

Volcanic Fallout is good and hurts Delver more, but I would say stick with AoG because of the Jund matchup. Just preference I guess.

And Mutagenic Growth is excellent in combination with Swiftspear because it more or less costs nothing. If they try to bolt her in response to you casting a burn spell, you can buff her in response to keep her alive.

A card I've been mulling over using is Leave No Trace for the Bogle matchup.

YamishiTheWickedOne I feel like Destructive Revelry works just fine.

You're probably right.

So I've been seeing CFB play Combust in their side for Twin. What do you think?

I wouldn't bother with Combust if you have Rakdos Charm. The charm does more for you anyway, it's basically an instawin instead of just killing on pestermite or deciever extarch. Also, I see why Growth would be good but I'm just not sure about the topdecking issue.

Rakdos Charm works better and growth is fantastic.
