Though don't spells go on to the stack as soon as they are cast? So wouldn't it resolve since if anything resolves on the stack, nothing new can go on to it? So why doesn't the original spell resolve before you can copy it again?

@_Grintex Once the stack starts to resolve you can still cast new spells. Players receive priority after each spell resolves.

All right, I have lost all confidence in my Mtg knowledge.

I believe you. I just feel ashamed.

Why don't you just make it modern legal? The only illegal card is Chain Lightning .

+1 from me. I really like the idea.

But are you sure that it will be just triple casting? Still there is always just mentioned it might be triple, but i believe you can do that combo for as long as you have the essential mana. Cast something, copy it, let it resolves, then copy the original spell, then let the copy resolve, and so on. Which gives you how many cards you want with Manamorphose and many mana.. Really nice. Love it.

Isochron Scepter to ensure you don't run out of spells to cast? also +1 if i haven't already. i forget

This is pretty great. I'm gonna try a variant of this in Modern with Kiln Fiends once I get a feel for my new burn deck.

Nice deck, and congrats on making top spot on May 7th. +1 from me.

Also you can't triple cast w/ only Blistercoil Weird , because the Lightning Bolt has to resolve in order to untap Blistercoil Weird , and so you can't copy it a second time because the Lightning Bolt has already resolved.... But you COULD get a quadruple cast with some Reverberate s and Blistercoil Weird s, or you could use Isochron Scepter . Look at my deck.

Basically, the triple cast doesn't work with only Blistercoil Weird and Dual Casting because the original Lightning Bolt has already resolved so you can't copy it again, and so has the copy of Lightning Bolt . But there are ways to get triple casts or greater, or just use replicate for infinite casts :)

I tihnk this would be an awesome modern deck with the replacement of Chain Lightning for Magma Jet

You need Price of Progress if you're going legacy. Blood Moon is something else to consider as well. Both are used frequently in mono red.

@ carysh Triple casting does work with just Blistercoil Weird and Dual Casting .How would Lightning Bolt resolve before Blistercoil Weird 's untap ability? when you cast Lightning Bolt it puts Blistercoil Weird 's untap ability on the stack and the stack breaks down from top to bottom so Lightning Bolt would resolve last. After Blistercoil Weird 's untap ability resolves I get priority and dual cast the original Lightning Bolt because it has not resolved yet. The example I used in my description is exactly how it works.

@ carysh here is the ruling:The key is ruling 1, the third one is why it is not an infinite combo

Solid deck, definitely more land to cast lots of spells. Maybe even a Flame Slash or two to get creatures out of the way, and Koth of the Hammer is fantastic for this sort of deck, if you like to play with planeswalkers.
