Beginners Deck

I think if you are just starting out a good deck to play that sometimes wins is a Tempered Steel deck.

Maindeck:

Artifacts
4 Glint Hawk Idol

Artifact Creatures
4 Memnite
4 Ornithopter
4 Phyrexian Revoker
4 Signal Pest
4 Steel Overseer
4 Vector Asp


Creatures
4 Glint Hawk
Enchantments
4 Tempered Steel

Legendary Artifacts
2 Mox Opal

Basic Lands
18 Plains

Lands
4 Inkmoth Nexus

This deck is relatively cheap to build and can race even the best deck in the format Caw-Blade! The deck isn't the pricey the most expensive cards being Mox Opal and Inkmoth Nexus. It's an easy to concept to grasp just attack with dudes! The deck is a little more complicated than that but I'm sure if you can handle managing the attack step and using your artifacts to turn on Idol you'll come out with a lot of wins.

I'll be watching the comments so if you have any questions about the deck let me know.
