Scry offensively!! Burn to control!! Cycle extra lands!! Smash people with huge unblockable, hexproof, doublestrike creatures!!
Main win condition:
Nivix Cyclops (or Spellheart Chimera) + Armed / Dangerous (+ Teleportal)
Basically you just want to keep the board clear with red spells, keep your creatures alive with blue spells, and then drop a 2-3 card combo with Nivix Cyclops they can't counter or block anywhere between turns 4-8. Alternatively, you rely on a stupidly large Spellheart Chimera from all the spells you just dumped to swing in with Trample and Flying for cleanup.
There's a lot of scry, and you can cycle cards you don't need with Izzet Charm, so getting the pieces you need to win isn't too difficult to set up.
I've been playing it against several decks in my playgroup and it's holding up pretty good so far, but the sideboard is currently untested. It's supposed to provide more options against control decks, and a better response to any weenie or token decks I'm hope.
Any suggestions are welcome! Definitely looking to try and make this as competitive as possible, while still retaining the fun, explosive combo potential.
