Somewhere there is a crime happening.

Basic idea is to drop etherium soldiers (and knights), slap handcuffs on the blockers, then swing. Ponder and Darksteel Pendant help set up the Stormcaller's Boon and drawing, which can be used to jump over blockers if necessary for a killing blow. Esper Stormblade is the key, a cheap guy who becomes really strong with any of the other multicoloured cards: Stormcaller's Boon, Ethercaste Knight, Deft Duelist, Ethersworn Shieldmage. Ardent Recruit is another good one. The deck has quite a bit of metal for crafting, and a 3/3 for W is great.

The sideboard either boosts up the defensive with more Pacifism and Vapor Snags, as well as the very useful War Report, which can net quite a bit of a life buffer. It also makes things a bit more aggro, allowing for Deft Duelist and Guardian of the Guildpact. These two are especially good against removal heavy decks. Both are also good against goblins, so are the reserve Legionnaires.

Word of Undoing is also incredibly useful with Pacifism, letting you lock down an opponent's difficult creatures with auras, then bounce them when you need to get rid of things more permanently and use the auras elsewhere. Works with Bonds of Faith, too, although that can only be used on Ardent Recruit, Auriok Sunchaser, and Ethercaste Knight.
