Depends on what decks we want to keep. We won't really be able to build a new deck without sacrificing other decks.
I would rather sacrifice the hematite golems, and build a sky blitz/dragon/wings deck than start building an

deck from the scratch.
So, drop some adrenaline, graboids, arsenic from first deck.
Reverse time, graboids from second deck.
pillars/pends from third deck.
Hematite/wings from fourth deck. (we still have some wings in another deck and salvage)
...
No idea what to discard from fifth deck other than the arsenic

Salvages:
1. dragons/blitz/pends?
2. blitz/deflag/wings?
3. pends or anything to discard immediately
