I'm not sure that Scizor is a render – but more to the point, I don't think 5ban is a bad artist/group(?) at all. They're good at capturing a variety of Pokémon in dynamic poses and doing it in high volume, possibly even on short notice (or some other factor that leads to Creatures being so amenable to commissioning so much work from them). Their work is fine. It's always just a question of oversaturation – even the undisputed master, Mitsuhiro Arita, would begin to grow tiring if he was doing this much artwork, for so many sets, for so long. Variety is the spice of life, and the TCG.
