I did the research regarding the two, Raiju is an ancient mythological beast from ancient times, it's also where Raichu the pokemon got it's name. Basically it was believed to be a fast creature, thus having momentum, maybe acceleration. Buraq is an old arabic winged horse type thing, thus similar to Pegasus, Buraq would thus turn into Pegasus with reverse time, as saying "Reverse Time" on something ancient, is reverse psychology, making it more upto date seeing Pegasus/Pegasi. Theoretically speaking however, there isn't much of a difference between Buraqs and Pegasi at all. And yes, having a Thunder dragon, would kind of be OP, as each element is OP in it's own way, Valkyrie Lance sounds absolutely amazing, I should've thought of that, thankyou for saying that Dawn to Dusk. That also contradicts my statement of the Lobo. Cthonic vs Gaian seems pretty cool, although Cthonic would go under Earth, as the word Cthonic translates from Kthonic (Greek) into Earth. Gaia was also the Goddess of Earth in ancient Greek, making it a Greek Deity, could be a potential name for a new False God maybe, or a new " God Card " which is extremely rare...I mean literally extremely rare.
