The most fucked up board villager line:

Using villagers can remove a lot of rng from the board at the cost of earlygame time investment into an iron farm & bad omen 

Build an iron farm, ideally adjacent to a lava pool, then continue with exploration. Either go to trial chamber for dispensers or use minecarts to build a chunkloader. 

Continue w/ the run as usual

Villager split:
Use portal strats & tnt to do a raid (like this: https://www.youtube.com/live/kU2jwaEKYXA, but you do NOT need to use pearls, just place a boat into the portal to skip anim)

Use hotv & iron from iron farm to trade w/ blacksmith villagers for easy emeralds

Armourer gives chain armour from hotv gifts, can get full enchanted iron/diamond as well
Efficiency tools from toolsmith 
xp bottle, redstone, & pearls from cleric 
You can roll weaponsmith or librarian for looting sword/book
Farmer gives cake & foods
Trade with cartographer for mansion map (you can level him up in nether to block monument & tc maps, just make sure to bring him back to overworld before master)

Of course all this overlaps w/ the multitude of iron heavy goals, should allow for more exploration time.
