I've done some digging and have found a pattern with Customize Sets:
New blade
New blade
Left-rotating dragon-like blade (dF 7S Z in God, bL1'D Cy in Cho-Z, EF St Tr Ten in GT)
First random booster prize (Layer) of the season (tW 1M Sp in God, cR 5C Vl in Cho-Z, CD Vn R in GT)
Based off of this, my predictions for the DB Customize Set are:
New Spriggan (Confirmed)
Rashad's blade
DB Fafnir, DB Longinus, DB Bahamut
Cyclone Ragnaruk
Of course, now that we've got customizable layers, the chips on the last two are tentative.
