Hearthpwn

This is my first deck upload which I've created there may be flaws with the deck itself but any feedback or suggestions is appreciated.

First of all the main part of this deck is Ragnaros the firelord i find him essential in this build as he is a really strong late game card that can win you the match. Early game you wanna focus on burst damage (Arcane Missles, Frostbolt) and i find it useful to have Polymorph to take out strong/Annoying cards that your opponent has.

(This deck has currently got me to rank 20 19 as a beginner so i have no idea what this game will be like as the rank increases)

Update-

Removed Spellslinger thought the card was too random. In its place i put Vaporize (Good for clearing the board) and i also added Ice Barrier (Great card only cost 3 manna and adds 8 armour getting you to late game with more protection)
