The "boring" part actually depends on the environment effect. In JFF Part 2, the Realm of Earth was clearly designed to promote the use of a rainbow deck (the 4 card limit being a serious problem for mono-decks). On the other hand, the Realm of Entropy in JFF Part 1 was designed for mono-decks and is nearly impossible to beat with rainbow.
Try to kill Mowgli with a rainbow and tell me again that it's "boring".
I admit that you are right but we were talking about different things. In the original game, players used to grind False Gods with just the same anti FG rainbow deck boosted up with sundials. If someone tries your trainer and fights against the new Gods, he will find that he has the best chances with rainbow decks in overall. There could be some expectations, for example Realm of Entropy, what you mentioned, but for most of the Gods (whether the old or the new ones doesn't really matter), you only have to set up some kind of standard rainbow deck and keep trying till you are lucky enough to execute the God. That is the thing what we (at least SG,YYB and me I guess) don't like and that's what I call boring. It's much more fun if people need to think of a really good (NOT RAINBOW) deck for each God. This would result different decks for all Gods and - imo - more exciting and challenging game.
For example, you mentioned realm of Earth what is "clearly designed to promote the use of a rainbow deck". You are right, the effects of this realm really make the non rainbow victory very hard. But, if you check it, you will see that I killed all the 3 Earth Gods with a non rainbow deck. It was great fun for me, and if I would have punched these Gods with the "ordinary" FG deck I would surely fall asleep in the meanwhile...
Anyway, I like the new effects and I don't mind if sometimes the rainbow decked victory is easier... I'll do it if I should. But everyone has to know, that he DON'T NEED TO USE a rainbow deck against FGs, there are other ways.
This challenge applies to everyone: I'll bow to the first person who posts a screenshot of him killing Mowgli with a rainbow deck.
Well, Mowgli is not an easy guy. Tons of creatures... Ulitharids... some Rewinds... huge Bone Walls... that crazy Discord... ugly
While I like challenges, I tried to do this one too, and finally I did it. It took me ~1,5 hours what is not that bad I guess. After I had my final deck, I only had to start 4-5 games to win once.

Yes, it's not the typical rainbow deck and not a typical victory, but no one said it has to be. And it's definitely rainbow.
Hands together no offense Chris, I don't say that the rainbow victory is easy as pie, moreover I say that a Mono/Duo deck would be much better.

I did that. You don't have to bow
And
it wasn't boring!
