We can currently pretty much chose which decks we want to play this round, the discarding / salvaging leaves us with many options.
Decks we MUST play:
2x Grabowinder
1x Grabbow
Suggested decks: (At least one needed, both works as well)
1x The Immortal // note: we don't have to play this one, but if we don't, we'll either have to convert it or use only 35 card decks. Using it is more risky than ever this round.
1x Entropy Duo
Optional: (One or two, depending on suggested decks)
Poison Stall
Devourer
Fractillon // Fractal will probably be converted due to never being used
Wings
Gravity Duo (Grav shield, Pulvy, BB is an awesome combo)
My random suggestions without much looking into the Intels or if it is possible would be the following:

--> Grabowinder (+ PA)

--> Grabbow

--> Grabowinder

--> Poison Stall

--> Gravity duo
// Surplus cards: The Immortal's light cards, because it doesn't feel right to go with this one against 35+ cards decks, also this will be a surprise when we launch this one in round 7 =)
