Nice table, my suggested salvage/discard/conversion (can be changed depending on decks we intend to build, but discard is low enough to not really be bothered by it):
Theonlyrealbeef: +6 Poison
Wizardcat: -6 Dark Pendulum
Mithcairion: -6 Dark Pendulum
Onizuka: +6 Horned Frog
suxerz: +5 Nova +1 Lightning
Jaymanfu: +3 Arsenic +3 Poison
Malignant: +6 Sanctuary
mrpaper: -5 Nova -1 Lightning
Conversion: -6 Horned Frog, -6 Sanctuary, -9 Poison, + 21 Dark Pendulum
Netto: +9 Darkness Pendulum (of which all 9 have already been sacrificed for upgrades), +3 Arsenic (2 Arsenics per Lockbow allow for more consistent damage, and we could potentially build two lockbows).
I might be dissappointed by the outcome, but I'm certainly not dissappointed in any of you. Great work so far, I hope the new information on opponents' vaults can bring more victory in future rounds. War is really starting now, and losses will be serious.
Be sure to tell me if you'd like to see certain details change.
