Will this work?

hey guys i havent played since shards zendikar standard so i dont know how this deck will hold up. the idea is to play a hob on turn three after a sig pest and a myr and then play hellrider turn four and swing for huge. i like the artifacts for metal craft so my removal is good and it can still work just tapping a creature to open them up and tthe hellrider will get the most use possible out of them late game for damage urabrask can completely stop them in their tracks and the sun titans should be a great way to refill the board especially after sweepers and swing possibly with haste ot battle cry and not leave me open. i dont like having no flyers, but yeah any suggestions?
