Poison is definitely good thing to have here, to avoid Hax and have cheap stuff to deal damage with. Steal is the issue. Discord could actually help to stall Dragons being played. Even if it gets stolen, Devs will pick up scrambled quanta. Also, Dagger will be upped. Thats 6 healing per turn, which would hopefully make him think twice before stealing a weapon.
I'm dead tired now, will look at vault remains tomorrow.
