Even if Paradox has a lot of copies of some cards, it also has a lot of non-quanta cards (towers are nearly negligible because they are heavily disfavored in the spins).
Paradox: 8 RoL, 8 Blessing, 8 Deja Vu, 5 Twin Universe, 4 Hourglass, 3 Miracle, 2 Mirror Shield, 2 Morning Glory (Total: 40)
Divine Glory and Decay are at the top because they have lots of copies of some cards, but also because they don't have very many non-quanta cards.
Divine Glory: 6 Explosion, 6 Glory, 5 AW, 3 Miracle (Total: 20)
Decay: 6 Pest, 6 Siphon Life, 6 Fractal, 2 Steal, 1 Dusk, 1 Eclipse, 1 Electrocutor (Total: 23)
We can also compare some other FGs that rate lower but still above Paradox:
Akebono: 6 Massive Dragon, 4 Overdrive, 2 Armagio, 2 Chimera, 2 SoFo, 1 Tower Shield, 1 Unstoppable, 1 Titan (Total: 19)
Gemini: 6 TU, 6 Phase Recluse, 4 Unstoppable, 4 Phase Shield, 3 Massive Dragon, 1 Immortal, 1 Lobo, 1 Phase Dragon (Total: 26)
Even if Paradox has more copies of cards, those copies are still diluted because of the large number of non-quanta cards.
