There are standard combinations:
O3M2: O3 is obvious why, M1 would be better but M2 still reasonable.M3 - too small probability to get heroes if any, and, the most important, with this build taking DEATH scale is very risky because you switch on some events like plague, which can be gamechanging if happened in your capital early turns.
But you will anyway take this combination if you do not benefit too much from turmoil like pangaea or gem income events, like Kailasa or you have dominion which kills your population, like LA Rleh and Ermor and order in a long run has no much sense for you as you are not going to have population.

If you play nations were you can afford taking Turmoil, you can generate much more points.

You usually take Turmoil 3 Luck 3. It is 40 points better then O3M2.It is one plus. The second plus - you can take a risk and take Death , even Death 3. Which would be VERY risky in first scenario. So you can potentially get 80-120 more points from death.(80 because with 03M2 you can still take D1 without fatal risks).
So you can generate 120-160 points more points which can be spend anywhere.

Some people like to invest it in Magic1 or Magic3. My favorite builds for some nations and some game settings include Drain 3.

I like T3S3L3D3 for some bless nations.

You get A LOT of points, and you can have awake sorceress , with research 30-40 from first turn (idea is taken from Baal'z helheim guide), and perfect sitesearcher later, with any kinds of bless you need. dominion usually will be low, so if you have a neigbour with high Dom , you should kill him faster then he domkilled you. But with yuor advantage in points and early research you are usually stronger then anyone around in early game.

As result your dominion is not very useful, it's minus.But it's weak,it's a plus. You build a castle where you find good enemy dominion (Magic1 or Magic3). And send your mages there (through flying boots or anything else).
Enemy magic dominion makes the land more magical, and it works for your mages very well. For free. Your first mages you produced in capital you use for expansion instead of researching almost from the very beginning, as you have good early research and in your dominion doing research with mages may be not the best idea,though sometime you do this as well.You also can forge items with mages.

O0L0 is a strange combination, I would never take that- you either need money critically from beginning , then you always take O3. Or, in very special cases (which are especially rare because its very popular to in MP to play with rich settings which make difference between order and turmoil even deeper) you take turmoil with luck. Maybe I would take O0L0 in case I would want to take death scale for points, but still needed money for early expansion (Order/misfortune is risky with death as we remember). But I don't remember a situation from real life I would do it.
