So, I was doing some random deck building when I came across a cool concept; using the Mage's Hero Power to trigger cards with Enrage effects. So far it's been doing rather well, I've had like a 70% win rate today, over something like 15 games. The idea is to keep your opponent's cards relatively low in the game with Hero Power, some spells (especially with a buffed Mana Wyrm), and then hide behind good taunters while you summon your Enrage-minions and hero power to hit them with just enough damage to activate without having them out on the front lines. Early game card draw is vital to find your good taunters, which is what the Novice Engineer, Arcane Intellect, and Acolyte of Pain are primarily for (hide the Acolyte behind a taunter, and you can Fireball it to 1 Hp and then run it into something for full value). If you start getting overwhelmed, I have a Mind Control Tech and a Flamestrike to handle minions, and Ice Barrier/Counterspell to stall a bit.
