This deck is based on Ejecty's Ice Wall deck. However, I was missing a lot of the Mythics, including several that he regarded as key. So I decided to splash in some green! Grinning Kolobok and Matryoshka help shore up my early game, and Sweet Spinerette and Spirit Stones help me abuse effects which return cards to the hand, aka "bounce" effects. This led me to include Brass Bouncer in the deck (hence its name).
The deck plays a lot like Ice Wall. You want to get lots of mana early on with Grinning Kolobok and Norn Datacore. It's often good to burn one green card early on, because Kolobok and Matryoshka are so good in the early game. However, the rest of the time you should try to burn blue and red cards, since those gems are more valuable- all your green cards only require 1 gem. How you proceed in the late game depends on what sort of opponent you're facing. If you're playing against aggro, simply fight for dominance of the board, and avoid playing Dragon's Teeth. If you're playing against a control deck, try to use Dragon's Teeth and The Stretcher to put your opponent on the clock- you will refresh your resources faster than they can remove them!
All of the mythics in this list are expendable! I actually find myself burning most of them in the early game, aside from Magnus Thorsson. You could generally replace them with any of the cards found in Ejecty's Ice Wall list that I took out. If you want to throw in some green, you could try artifacts like Samosek, the Living Blade or Shroud of the Pit, which also only cost 1 green gem. If you don't have Spirit Stones or Brising Necklace, you could throw in more copies of Sweet Spinnerette. However, I would caution against adding too much green: you still want to be able to pull off your blue and red plays consistently.
Many of the rare artifacts, though, are core to the deck's identity and irreplaceable. I don't think the deck would really be the same without Norn Datacore, Dragon's Teeth, or The Stretcher.
