Interesting! I've always wanted to build a deck like this, but never heard of the Isochron Scepters, or had the Sigil of Sleeps to do it.
+1! It's good to see someone can make this work like I'd like.

It's for sure a very fun deck. The only problem with it is it takes till turn 3 to really be able to do much, but it has more than enough burn to take care of any problems before then.

You need way more red mana for consistency. I'd definitely swap some of those islands for Steam Vents, and maybe even throw in a Scalding Tarn or two for safety's sake. The Cunning Sparkmages are nice, but compared to the Cinder Pyromancers they're definitely not worth much, consider running Monastery Swiftspear or Blistercoil Weird instead? In fact, if you go with the Weirds, it might be worth going with Paradise Mantle too so you can cantrip through your deck with them.

Definitely a ton of fun, might run a version of it myself.

I play tested the deck and a problem I found with it is lack of card-draws. Other than that is a fun concept and will definitely piss off my friends. +1

Did you put Quicksilver Dagger on either Blistercoil Weird or Cinder Pyromancer? They untap when you cast a spell and then you tap them for their do one dmg and draw a card ability and it can easily cantrip into a lot of draw and dmg. Needle Drop untaps them both, does a damage, triggers Guttersnipe, and replaces itself with drawing a new card; all for one mana.

@Salmidood

Also, Magma Jet and Spark Jolt help scry into the cards you need to finish up the combos. Scalding Tarn also helps eliminate dead draws of lands when they are no longer needed.

@wants2belink

Id really like to add Paradise Mantle to the deck but the main problem i see is it becomes a dead draw that can mess up the cantrip tempo and i have no idea what to take out for it.

What do you think?

@_-Orvos-_

Looking at it now, I definitely agree that Paradise Mantles would be a bit much. If you really want to go that route then you're essentially going to be playing Storm but with the Blistercoil Weird + Paradise Mantle interaction being your mana engine instead of Desperate Ritual + Pyromancer Ascension . At that point I'd really completely retool this deck, throw in lots of 1 mana spells like Cerulean Wisps, Crimson Wisps, and Aphotic Wisps, as well as Mutagenic Growths for a little extra pump. You won't need to make a full storm count of 14-18 since you'll be swinging in with the Blistercoil as well, but what you gain in versatility you're going to be losing in reliability in that regard.

As for the deck right now, I'm not too sure on the lack of serious card draw here, dropping your hand by turn 3 and then just relying on top decks isn't the best way to go about things. I'd probably cut out the Quicksilver Daggers and the Sigils, replace them with some combination of Gitaxian Probe, Serum Visions, and Electrolyze.

Probe is always great, and a turn 1 Probe on the play will basically tell you exactly what you need to wait and watch for later on. Serum Visions is a great card to dig three into your library, worst case scenario you're dumping stuff you don't need at the bottom of your deck or just waiting to draw the answer with your next spell or draw step. Electrolyze pulls the double duty of burn and draw, and in my mind it basically fills the same kind of role as Magma Jet since a Scry 1 is kind of like drawing half a card.

Oh, and Spellheart Chimera might be worth looking into as well. Your first few turns are going to be dumping instants/sorceries anyway, might as well get some extra value out of them. However, they are kind of competing with the Blistercoils and the Pyromancers for room, so maybe drop one of each and throw a pair in. Worst comes to worst they eat a bolt, but they're still going to be something like 3 mana flying, trampling 5/3s for the turn or two they're out early on, and they'll get terrifying later, easily 7/3 or more by turn 6 if things are going even average for you.

I just need to double check with you because others seem to have missed it. But you do see the card draw that comes from putting Quicksilver Dagger on either Blistercoil Weird or Cinder Pyromancer right? It makes it so every red spell or instant or socery draws me a card.

I dont usually drain my whole hand of cards becaause of the mechanics of the deck im usially drawing as much as what im playing.

I see it, but personally I think it's a little unreliable. I wouldn't go for it without some fairly extensive testing.

Noxious Revival can be fun.

Just to raise your cast count.

Example: Gitaxian Probe then Noxious Revival to draw it again.

Faithless Looting

Pyromancer Ascension

Pyromancer's Swath

If you're only playing casual, you can use High Tide, Seething Song, or Rite of Flame for mana acceleration. There's also Simian Spirit Guide, which is legit in almost every format, but doesn't add to the Storm count. Desperate Ritual is okay, though not great without Goblin Electromancer. The Paradise Mantle idea is pretty solid, though. If you do go with Tide, I'd run some more blue cantrips, like Serum Visions and Ponder. I don't think you're missing speed, I think you're missing a balance between cards that make you mana, cards that draw cards, and cards that do damage. If they aren't in the right proportions you'll stall out on one front.

Hey. To be honest, I'm not a fan of Serum Powder at all. You can already mulligan as is (and with this deck, you can safely mulligan down to four as long as you can get your pieces), and it can create some awful situations (eg: two Blistercoil Weirds in your hand, but no land or Paradise Mantles. If you use your Serum Powder, you're tossing out half of your combo engine.

Otherwise though, pretty good. Personally, I think you're really close to making it modern legal, but if you're just playing with friends, maybe there's no point.

(Also: Ideas Unbound and Faithless Looting are two of the best cards for this deck. =)

This deck is going to stay casual. Its going to be that deck that a person uses when someone made them angry last game.

Manamorphose?

oh and maybe Peek, Seething Song, Desperate Ritual, Pyretic Ritual, Rite of Flame, Pyromancer's Ascension, Past in Flames, Cascade Bluffs, Goblin Electromancer, Thought Scour, Grapeshot, Empty the Warrens

Desperate Ravings is better than Faithless Looting cuz it nets you a card

No it isn't. With Faithless Looting, you can dump unwanted cards; with Desperate Ravings you can't control what you drop.

Speedmew223 those are all good cards but this deck works great as it is right now. The only thung im even considering changing out is treasure cruise because it is somewhat situational and is a dead card in my starting hand.

Named_Tawyny you are correct! But Cephalid Coliseum does the same thing but with three cards. And there is so much scry in the deck that digging with draw/discard isnt worth it.

Cephalid Coliseum doesn't untap your Weird though.

I guess I got carried away with all the directions the deck could have gone. But U/R Storm is pretty fun, you should try it sometime.

This deck can generate enough mana that by the time i need to ise cephalid coliseum i wont meed to tap my weird for mana.

Personally i think this deck trumps a BU storm but then again i am using a lot of banned cards which is why this is staying casual.
