For the Company of Exiles Event:
This deck is designed to play control/counter to many of the decks that should see play, with (effectively) 10 backlashes (counting choices) that then spawn units for you. Also leveraging Rain of Frogs and Unexpected Results to both disrupt your opponent's plan and give you more board presence--keep in mind, Firebomb will give your opponent's free 1-cost units.
Herald song's are effectively echoed 2-cost Crafty Yetis, and if you trigger Privilege of rank it's 2 power for a 2-cost unit, a 3-cost unit, card draw, and 2 Justice sigils.
Result: 7-1 due to a disconnect. Very effective deck at keeping threats off the board until decimate lands you a Scourge
