Fridge / Cardfight!! Vanguard G

• The existence of G-Units is a big whopping pile of Fridge Logic when applied to the original series. With flashbacks cementing their existence and usage (both strides AND G-Guardians) as far back as when Shin was part of the pro circuit, it raises the glaring question as to why G-Units were conspicuously absent throughout all of the first four seasons. The issue is never addressed, so the answer seems to be just don't think about problems in the timeline.
• When Leon fights Chrono during the G Quest, he uses a deck focusing on Blue Wave cards such as Tetra-Drive Dragon, his ace card during the latter half of season 3 rather than a deck focusing on Maelstrom, which not only was his ace card during season 2 but is arguably a more iconic card for the clan. However when you remember that Leon only used Maelstrom when he was an antagonist, it becomes more understandable.
• Why unveil the G-Guardians at the Ultimate stage of the G-Quest rather than during the G-Quest? In-universe, it's a marketing reason, introducing G-Guardians with two of the top teams in an exhibition match will show its power to the fullest extent.
• Diffriding can be seen as a derivitive of Psyqualia. With Psyqualia, it's said that it connects the fighter to their units on Cray. Diffriding goes the other way around, it allows a unit to connect with their fighter and inhabit their body as if they were their fighter.
• Am using a Granblue deck instead of a Megacolony one may seem odd, considering that Luna uses Pale Moon (which fits her moon motif), as the former doesn't fit with Am's butterfly motif at first glance. However, what is a butterfly often symbolic of? Rebirth, which fits perfectly with Granblue's playstyle of reviving units and ties into Am's goal of reviving her parents from their coma.
