novabow discard: 7 pends leaves 23 cards, leaves 8 cards to keep.
Discard ghosts. This deck obviously failed. (-4)
Discard explosions. We have 3 more after this. (-2)
Discard eternity. We still have 1, and we can't really make a deck with it anymore, anyway. (-1)
Without the ghosts, we cannot make a dedicated nightmare deck anymore. I think keeping at least 1 for either the paradolls or (if we go this route) the novabow is a good idea. We can discard the other two nightmares.
Discard 2x nightmares. (-2)
Cards remaining:
Looking ahead at the salvage from light, we can discard 1 lightning and salvage one back.
Discard 1 lightning. (-1)
5 nova, 5 mummy, 1 nightmare, 1 lightning, 1 fog (keep 8, discard 5 )
We can get a nova back from light as well, which would either let us spare 1 nova or put us back at a full 6 complement. We have to at this point either take a hit on novas or mummies (or both), and there is not much we can do about it. If we discard the novas, we have a bunch of worthless cards in vault (lycan, graboids, sundials) that we could suicide with. If we discard the mummies, we're getting perilously low on death creatures.
Discard the other lightning (we'll have 5 still after salvage), discard the fog (only good in novabow, and it's just 1 card), discard the nightmare (don't really want to, but so be it) and discard 2 mummies.
-1 lightning
-1 fog
-2 mummy
-1 nightmare
Leaving us with:
Discard 15
2 mummy
1 fog
1 eternity
4 ghost
2 lightning
2 deflag
3 nightmare
(and keeping 5 nova 3 mummy)
I don't think there's any other way to reasonably do this, as painful as it is. We CANNOT spare more mummies, and I think we need to keep the novas. That means everything else goes bye bye.
