Some pretty hard choices there, let's get somewhere started for a discussion:
Salvaging:
- 1st Deck:
3 Wings
3 Lightning
Alternative: 6x Lightning - 2nd Deck:
3 Heal
1 Druidic Staff
2 Adrenaline
Alternative: 2x Wings instead of Adrenaline - 3rd Deck:
4 Crusader
2 Maxwell Demon
Alternative: 3x Pillar, 3x Pend
Discard:
- 1st:
6 Devourer
4 Steal
1 Dusk Mantle
1 Pillar
// Scrap one of the two Devourer decks. - 2nd:
1 Momentum
1 Arsenic
1 Lightning
1 Purify
3 Stone Pillars
1 Lava Golem
4 Graboid

// Most of these things are already plenty in our Vault. - 3rd:
6 Pillar
6 Pends - 4th:
2 Morning Star
1 Animate Weapon
4 Pillars
5 Pends
// Keeping both immortal. They are just too good (and lame). The Morning Star was mostly only a hindrance anyway and if they expect this deck, they WILL bring healing now.- 5th:
1 Vampiric Stiletto
1 Fog Shield
1 Forest Spirit
1 Lightning
1 Momentum
2 Graboid
3 Pillars
2 Pends
// Same as 2nd
