It looks like there are several whole, original Beyblades there that simply have their parts mixed around; notably, Burn Phoenix is assembled with Inferno instead of Burn, and Inferno Sagittario's parts are scattered all over the place.
The unlabeled originals look to be, from left to right, moving downwards:
-Some mashup of another Flame Sagittario and a Rock Leone
-I can't tell, maybe a Cyber Pegasis recolor? Looks pretty though :3
-Ray Unicornio
-Probably the rest of Rock Leone, mixed with Inferno Sagittario
-A Beywheelz ring from the Destroyer Dome? Has Cyclone Herculeo's parts
-Rock Scorpio
-Rock Orso
-Some kind of XTS Tornado Battler
-Galaxy Pegasis
-Storm Pegasis recolor?
The loose parts include:
-Burn
-Rock (x2)
-A beautiful Lightning L-Drago recolor
-Sagittario
-Virgo
-105
-145
-D125
-GB145
-WB
-HF?
-B?
-S (x2)
Even if the parts weren't competitively useful, $30 for a lot of this size is a great find. But this lot contains a lot of useful parts, and contains enough for several competitive Limited combos.
