So when I try to hire a new mercenary unit with the Condotierro, it doesn't work. It says "Needs 2 Units" but doesn't specify WHICH two units. Can anyone help me out here?

Needs 2 money sources e.g Money couriers.
But I don't recommend using those abilities.

That seems rather useless then. Why even include it, if nobody thinks it's any good?

It's essential part of maximizing production on endgame, when one has mines.
It's just not very cost efficient to produce money couriers, but when you already have them - it's another story.
Those abilities can also be used to counter unknown enemy forces.
You take scouting unit and just behind him send condotierro with 2 or 4 money couriers.
When closer to enemy base you summon units countering enemy forces.

and when you see the enemy then youll know what units will you use to counter them

It is pretty good once you get mines going. You only need to invest into one or two miners and you will soon be producing units faster, building faster and taking advantage of abilities like this.
