Scorpio and Gemini are probably the best False God names, not only because of the cards that actually reflect their abilities (Deadly Poison and Twin Universe respectively), but also because they're 2/12 Zodiac signs. I'll go crazy when they introduce a False God named Sagittarius, Libra, or Capricorn, as those names are truly unique (and sound devastating as well).
{if they have Taurus, I'll be ecstatic as that's my astrological sign XD}
I don't think the reasons for the 'worst' false god names are valid. People are forgetting about Eternal Phoenix (uses the Minor Phoenix card) and Graviton (has Graviton Fire Eaters) when it comes to 'having cards that match their name' exactly, but because of how powerful the gods are, they're 'respected'. Sure, Miracle is the only one with a card that mirrors it exactly, but it makes sense for that FG to have it, and it sounds okay.
Dream Catcher, Osiris, Elidnis, Hermes, Neptune, and Seism are some very interesting ones also.
The worst False God names are some of the ones I've seen in the 'Make a FG!' competition.
Whoever suggested 'Moo Cow' as an ACTUAL False God seriously needs to be virtually slapped in the face.
