Proposal: Drop Righteous Fury (it hasn't worked against the decks it was supposed to work against), and save as much of the other two decks as possible, which will be almost everything considering we're only at -24 for this round. 
Can't really achieve that perfectly, because we need to drop 15 from each deck, but lets try:
From Angle-gate we can drop 15 pillar/pend, and then recover them from salvage -> convert (21 total salvage leaves us with 6 more, see below)
From Righteous Fury we can drop the 15 non-light cards.
From Fire-stall we can drop 11 light pillar/pend and get back 6 of them (4pillars+2pends) from salvage -> convert, leaving out 5 pendulums that were also in Fury, so that part is OK. But, we still need to drop 4 additional cards from Fire-stall that we cannot recover.
From Righteous Fury, I'd drop Photons instead of Deflags, since we won't need as many photons and the deflags can go into firestall. And we definitely aren't dropping Rewinds! In addition, we have a spare fire pend and RP (so glad I salvaged that last round) in vault, so that's two more cards we can drop.
Summary:
Drop 15 pillars/pends from Angel's Gate
Drop 9 fire cards, 2 earth cards, and 4 photons from Righteous Fury
Drop 11 pillars/pends from Firestall, plus an RP, a Fire Pend, and... two more cards?
