First, the game internally ranks your daemons based on their total stats (Att + Def).

Then it checks your available AS and DS. It only uses DS up to 2x your AS. If you have 50AS and 110DS, it will only calculate based on 100DS.

Then it selects an army based on the ranking until it uses all of the available combined AS+DS (50+100) to continue the example. If your top 10 daemons cost a total less than 150SP, then you get to use them. If your top 10 daemons cost 180SP, then the last few spots might get filled by low cost Wind Weasels, Kaedes, etc (instead of good daemons) until it uses all 150.

If you chose to attack, it reduces the amount of AS and DS by 1/2 of the amount used to summon the army. After a battle with this crew, you'd have 25AS (50-50/2) and 60DS remaining (110-(100/2)).
