While it's not complete, the idea was that you would have rage extractor out then get out the moltensteel which would do 6 damage to the other player each time you bring one out.  Then you could mutagenic growth it, play another, give it protection with apostle's, bring back a creature, play a scurge or a the wall and deal non-combat to the opponent - all the while this could end boosting the chandra up substantially if you get it out early enough.  The phyrexian unlife is to give you that extra protection for when you knock your health down really far doing all of this.  


In the sideboard there is a platinum angel which I thought might be good but the game may not last that long.  Also, the dismember is probably one of my best option sideboards as you can play it, and hit a creature or player for 3 (free lightning bolt) then slap on the -5/-5 coutners on another creature which results in either double removal or a buff to the chandra.


Bear in mind these may not be the best combos and this deck is just an idea I threw together.  Any constructive criticism is welcome.


Thanks for looking and I hope I answered your questions!
