We definitely need to salvage from Life so we can run 2 grabbows (which we are 2-1 with) and 6 EQs (which we also like). From Earth we can salvage 5 Dimshields and 4 Fractals. The only thing Light has that Earth doesn't is cards for a Light duo, which we won't want, and cards for a PU deck, which I don't think we need.
Since time is running out, we need a decision now, and I think Light is the team we do not need to salvage from (But you can change this if we still have time).
If we decide to go with this plan, MrBlonde, make sure to remove your screenshot and make it clear to the warmasters that you are not going to receive the 3-card bonus salvage.
