Asura Kaiser and Stern Blaukluger, and cards from the manga.
Historically these two were the Novas' primary competitive vanguards prior to the Beast Deities taking over, and EB09 will conclude Asura Kaiser's long search for a supporting grade 3. Described as "the perfect booster for people just starting or have been fans for years!" EB08 will allow Nova Grappler cardfighters to build decks "of Real Robots based on the Blau Series," suggesting that these decks will consist solely of Blau support units in a revitalization of their BT04 play style.
Like Mystical Magus before it, VG-EB09: Divine Dragon Progression will feature primarily cards from the manga, this time focusing on Kai Toshiki's Kagerou cards from chapters 17-25. Gaiarth Dragon and Cruel Dragon are confirmed to be printed in the set, along with reprints of Berserk Dragon and Bellicosity Dragon. Most surprisingly of all, Kai's grade 4 "Transcendence Dragon, Dragonic Nouvelle Vague" will be printed in the set. Gaiarth Dragon (a portmanteau of "Gaia" and "Earth") was originally known as the grade 2 Dragonic Gaiarth in the manga, and unlike most grade 2s had the boost ability instead of intercept, but contributed 0 power when boosting and increased the critical of the boosted unit by 1 instead. Kai first used this card against Ren in chapter 17, where he used it to increase a rearguard Dragonic Overlord's critical.
EB09 will feature 23 reprints and 12 new cards, with 3 RRR/5 RR/8 R/19 C and 4 SPs. Dragonic Waterfall may be one of those reprints, as it is Kai's finishing card in the manga equivalent to Aichi's Exculpate the Blaster and Ren's Phantom Blaster Dragon.
