Glimmer of Genius. Grip of the Roil. Savage Alliance. Pyromancer's Assault(4 of them. DO IT), Catharic Reunion, Drag Under, Galvanic Bombardment

alright, dynavolt tower as a maybe, we are going to be fiddling with instants and sorceries a lot. Throw it in there. Harness the Storm. Thermo-alchemist. Geistblast. Mecurial Geists. These are all the FUNSIES cards. We'll see if we can work them in.

Alright, what I see is a burn deck. You want to do a burn deck. BUT, you are trying to do too many things at once. What you need to do is focus down first and add some better gears and cogs. I see you want a standard 'UR' deck, but you have too many creatures and too many expensive pieces. 

I want you to drop EVERYTHING that is 6 and over except Gearhulk. Gearhulk is fine. None of them are going to win you the game directly. Yes, even chandra. Too little, too late. You awnt your mana open.

Okay, your big best cards here are Jori En, Stormchaser Mage, and Nibilis of Frost. You want to build around these. Drop Inventor's Apprentice and Gremlin for now until we find better 1 drops. Drop Fiery Temper, what Mica said, you don't have enough discard to make them work.

Drop all your enchantments. Aether Meltdown is okay, but we'll find better. You don't need Oath or Dampening Pulse
