there's actually three parts...
1. Speed. Without them, the deck is a bit slow, though still playable.
2. Burrow, as was guessed. Those things die FAST if my opponent gets quanta out after a couple rounds of being drained
3.When I steel some of the rare weapons, such as lobotomizer, I'd like to use the abilities.
I did do a slight revision, removing the gargoyle, which sped it up some, and it seems to work well with 3 novas, rather than 6.
