Hearthpwn

Incomplete Guide. Make sure I finish by asking questions.

This deck is more aimed at newer players who don't have much of a collection, but also works with more experienced players as they can replace some of the cards with slightly better cards.

This deck revolves around board control. You have some good minions in here, as well as some spells to cripple your opponent.This deck is pretty versatile in what it can do, it has an answer to almost every situation. Arcane Missiles serves as early removal, Fireball for mid-game brutes and Polymorph for the occasional Legendaries.

Tips:

Don't waste Fireball on anything with less than 5 Health.

Don't waste Polymorph on anything worth less than 4 mana.

Don't Flamestrike on less than 2 Minions at a time (duh).

Using your hero power on Gurubashi Berserker makes it a lot stronger for 2 extra mana.

Don't play Arcane Intellect on Turn 3 if you have other choices.

Card Replacements:

 Shattered Sun Cleric: Shattered Sun Cleric, I believe, is a brilliant card. However, if you play it by itself, it loses value. I prefer using Harvest Golems. They have one extra stat point compared to Shattered Sun Cleric and don't require any other board presence to function properly.

Arcane Intellect: Arcane Intellect, is not my favorite, I prefer Acolyte of Pain. If you play Arcane Intellect on Turn 3, generally, you're toast. Acolyte of Pain has board presence and synergizes well with your hero power.

Gnomish Inventor: This is a good card, I just enjoy using Piloted Shredder a lot more.

River Crocolisk: If possible, replace with Haunted Creeper or Annoy-o-Tron.

Sen'jin Shieldmasta: Arcane Nullifier X-21 is slightly better. On a Taunt minion, Spell Immunity is more useful than Attack power.
