Unwinding Clock and Shimmer Myr work well together. Feldon of the Third Path helps bring back artifact creatures for a turn. Cheat out a Magister Sphinx to make their life 10 and Conjurer's Closet to trigger your enter the battlefield effects again. Sphinx Summoner is great search. Spine of Ish Sah combos well with Panharmonicon and Goblin Welder. It's best to find ways to cheat out artifacts.

I would recommend Krenko, Mob Boss to make good use of your Purpheros. Mybe use an Eldrazi Monument just because that's pretty mean. Overall this is pretty good.

I used to run Unwinding Clock and it wasn't as good as I thought it would be. I usually don't attack with my creatures and only few of my artifacts (accept for mana rocks) tap, so I took it out. As I said before I never attack so Feldon of the Third Path is pointless, especially because I usually can bring back creatures from the graveyard if I need them. Magister Sphinx on the other hand is a great card, but it puts me in a situation where I have to pick the player, and it draws too much hate. Conjurer's Closet would work well with Breya though, but CMC is waaay to high. Sphinx Summoner is just too expensive tutor. I also used to run Spine of Ish Sah, but it always ended up as a first card to discard. Thanks for your insight!

Goblin Welder is the only Goblin I run, so Krenko, Mob Boss wouldn't be a bomb in this deck. Purphoros, God of the Forge deals so much more damage when I simply blink my creatures. Eldrazi Monument got too high CMC. Thanks!
