*Quick ruling because I need to go, but we're already halfway through deckbuilding so SOMETHING needs to be done. Subject to us changing it later.*Gravity may add 4 cards discarded from their round 5 decks as Event+ for this round. These same cards are then removed as Event- during their next round's SDCP in addition to any other discards or penalties. Gravity salvages 3 cards and discards 14 from matches this round. Further adjustments to their Vault may apply once their Vault has been properly audited.
How about next war, instead of being salvage small with each win and discard lots with each loss, is you gain and lose equal each time you win and lose, respectively, and the bar for survival is constantly set higher each round?
