Is there a place where MTG posts the lore?
By Jove, why would you do it to yourself man?
Myself, I just stick to the basics, which means whatever I can piece together from the flavor texts. In the beginning there were two brothers, Sasha and Misha, and they had some sort of beef.
Then came Urza who had this school of magic together with a problem student Tereferi. It all wraps up with Gerhard hauling ass on a skyship. He banged many womyn, and there was some furry shit going on,
but alas what happens on the Weatherlight stays on the Weatherlight.
There. No more lore afterwards. There really isn't. Just read this if you need further convincing:

like to mix triomes with the eldraine special ability lands so they come in untapped, I got a full set of those and the temples.
Yep, just like with checklands, it's good to have enough lands with a "basic" type to make the drawback less of a hindrance.
You can probably do some math here, but my rule of thumb is to have at least 16 lands with a "basic" type. 18 if you want to be extra sure.
This should keep you on the safe side and barring some really unlucky draws, the lands should come into play untapped when you need them.
There are pretty much three considerations for using the triomes in historic.
1. Do you need three colors of mana? If not, don't use Triomes, cause you should be able to get better results with pathways, fastlands, shocklands and checklands.
In standard, I would use triomes in two-color decks to compensate for missing pathways, but there are many other options in historic.
Now, if you want a 4-5 color deck (viability aside), Triomes will probably be your bread and butter if you want to get a full set of colors out consistently.
2. Are you playing aggro? You don't want tapped lands in aggro. And you probably won't be playing three colors in aggro. Three colors will probably push you towards midrange.
3. How relevant is the cycling ability for your deck? If your curve stops at three lands, you won't be cycling too much. And if you're flooded, using a land that cycles for 1 or 2 mana is probably a better idea.
If I were to craft Triomes exclusively for Historic, I would start with one of each and probably not go above two copies.
