FJP Commando

Based off of ManuS' FJP Plate deck, I removed most of the legendaries and replaced them with cheaper, more aggressive cards. I made this deck with the goal of slowly building into the full ManuS deck until I realized that this deck was still pretty good.

Unseen Commando and Mirror Image are the core of this deck. Just stack as many Commandos as you can as fast as possible. If you have no Commandos in hand, just copy the best unit you have. Don't be afraid to sacrifice hp early in a match to preserve your board. Unseen Commando and Whirling Duo will stabilize the situation pretty quick. These two cards usually form the main attack force. The higher cost cards are for wallbreaking.

If you suspect that your opponent has some removal in his hand, it might pay to wait until after the attack phase is over before playing Commandos.

EDIT: I reached Diamond with this deck by winning only once a day for the daily pack. It got very difficult towards the end of the month when Hailstorm and Harshrule started to become more popular.
