The deck is trying to make it very hard for your opponent to kill your big threats.
Darkveil Agent is critical to this plan, since a lot of cards in the list are Unseen. The others tend to already have Aegis naturally, and many have 2 battle skills, making
Unseen Commando's textbox extremely relative.
The sideboard isn't even close to real, but it's where I'm storing thoughts currently. I'll tweak if/when the deck is good enough to deserve it.
