Nice post Safra.
I would like the more consistent decks to win over the ones packed with generic value cards (which tend to be 3+ color decks). And I try to make that happen by focusing on synergytic effects versus raw power cards. But I want to cater to the raw power guys too because not everyone wants to create complicated decks and I can appreciate that desire. I just want those raw power guys to have to make hard color choices.
Thragtusk is just not the droid I'm looking for personally.
Devotion was a mechanic that I was really excited for because it helps with what I'm trying to do. But outside Thassa, Purphoros, Rofellos (sort of), and Grey Merchant, I don't have tons of incentive for mono (or heavily mono) color decks unfortunately. It's still more an idea than an actualilty. Hopefully we see more cards printed in this vein though so I can keep pushing this concept forward.
I'm not much into the actual lore of the game, but the fundamental identify of the colors and how that translates to what kind of mage you are playing... It might sound contrary, but I really dig that part of the game. And it likely stems from my role-playing background.
EDIT: More on this idea of having to choose primary colors. I'd love some flavor of mana system where the more colors you played the few cards of those colors you had access to. So for instance, all CCC cards would be locked out as soon as you went to 2 colors, and all CC cards would be locked when you went 3 colors. Something along those lines. Clearly not anything you could put into Magic at this point, but I dig the idea of getting access to more powerful effects in a color by focusing more on it - hence why devotion is so appealing to me.
