Jesus. I want to try this out. I've run a creature light deck similar this before...but this...my jaw dropped before even reading your description. As for maining pyroclasm, other than dropping a swords to plowshare, I'm not too sure on what could possibly be taken out without messing with your consistency.

Thanks! Yes maybe one StP could be replaced with a Pyroclasm. They serve similar purpose but it adds some flexibility :)

My legacy elf deck has been on the receiving end of a Pyroclasm, turn two, just before going infinite into Emrakul. It wins games and really turned that around against me. Something StP wouldn't have been able to do that early. So, if anything, it would be a great sideboard card for elf, affinity, goblins, and even some Naya builds. StP would still be better against the majority though, i think.

Yeah I think StP might be better than pyroclasm mainboard. I think i keep 2 in sideboard along with 2 Electrickery. I added 2 Propaganda to my main board to deal with creature heavy matchups.

Have you considered dropping Plateaus for more blue duals?

bigguy99 well i would like to have more Tundras and Volcanic Islands, but I cant afford it at the moment :)

But ideally, what would the spread of duals look like?

Probably 3x Tundra, 2x Volcanic Island, 1x Plateau, 4x Island, 1x Mountain, 1x Plains, 8x fetches
