my suggestions:
from hrmmm: 4 x sanctuary, 2 x fahrenheit.
From Zeru: 6 x fire lance (this way we can bring 2 firebolt decks if we want)
From Hisar: Nothing that vital - I vote we just take 3 quint, 3 wings and then discard them since we need to discard 17 cards for all the upgrades we used.
From Spike: Again nothing vital and the time cards are useless to us. Chaos power could be good if we have a plan for it... But I don't so unless someone comes up with one... I vote we take 2 x discord, 2 x antimatter, 2 x chaos power and discard the antimatter and chaos power.
Discards:
18 life pendulums most likely and then convert some stuff. We need to discuss what we discard and convert though. Overall, We lost 18 cards, sacrificed 17 cards, and won 30 cards for a net loss of 1 card (if I did the math correctly). That means whatever we salvage will actually be replacing something we get rid of...
