So far I've only been brave enough to test this in Gauntlet, where the AI is bad at playing around it!
The goal is to use Azindel or Mask of Torment to get absurd amounts of power so you can Last Word + deadly Lightning Storm + ultimate to win. Colony Matron works with both enablers and is generally your best card. (That might say something about this deck I don't want to admit.)
Shadowlands Bonepicker is your backup plan, as its not hard (...in Gauntlet) to activate him two or three times a turn.
If there's any part of this deck that actually deserves to see ranked play, its probably the tech of Stray Into Shadow with 12 5-toughness dudes. Alas, there probably just aren't enough 3- and 4-toughness dudes around to justify it.
