I´ll try to give you some advice on how to play this deck

Torch : This card is very versatile, can be use like a removal spell or a burn spell
Purify : This card is a very good removal spell, even if you can´t kill the creature, silence might be good depending on the circunstances
Temple Scribe : We are going to use this little guy, to block on the early game, draw cards an also win life, its awesome
Vanquish : big creature removal
Amber Acolyte : mana fixer
Sword of Icaria : Most of the time, we are going to use this as a removal tool, but you can try to put some pressure on the oponent, specially if he/she is playing control
Auric Runehammer : This card is an awesome removal tool, also is one of the best card that you can search with Rise to the Challenge
Rise to the Challenge : We are goning to use it almost every turn 4, because we lack of minions of this cost, if you want to play safe, just look for Auric Runehammer, if you want to be aggresive look for Icarias or Worlbearer Behemoth, also if you are lacking mana, go for Amber Acolyte
Harsh Rule : Massive removal, be careful when you use it, because is a greater defense tool against aggro match ups
Marshal Ironthorn: This card can help you to ramp up a bit, but most of the time you want to play it after Worldbearer Behemoth or Mystic Ascendant
Worldbearer Behemoth: This card is simple insane, is stats are crazy and also clean your deck from powers
Flamestroker : Personally I love this card, you want to play this into every control match up
Heart of the Vault: Greate card, can be use to put some pressure on the table or to remove some small enemy creatures
Mystic Ascendant : This dude is insane to, i do not recomend to play it if you are not going to play a power after
Icaria, the Liberator : Another insane creature, this card as everything you want in a creature card

Thank you for reading, if you have any idea to upgrade this deck would be awesome, also if you don´t have any of this cards, ask my in the comments and i try to help you!
