DCO is a technology which automatically evaluates every creative aspect of an ad and applies them to various audiences through machine learning. With Dynamic Creative Optimization, all you need to do is to upload all of your creative assets (headlines, texts, descriptions, and images) and select one broad audience to be placed into a single “pot”.
Example: You set up 3 headlines 2 images and 4 texts in one ad. Meta will serve the best combination fits to a concrete group of persons. It means that for:
women, 18-30, goes headline1, text3, image2
man, 30-50, goes headline 2, text1, image1
and so on.

DCO carousel
DCO carousel uses your texts and images to create best performing combinations of cards. All cards direct to one destination URL. FB will display 3 to 10 cards in the ad. Every image can be paired with each text (image1 with text4 with headline2). Therefore, try to use more universal texts.
Group rules
You can assign certain elements to groups and ensure that those elements will be displayed together. This feature is available for Single Ads.
Example:
Inputs:
text#1: red
text#2: red
text#3: blue
text#4: -
----
description#1: red
description#2: blue
description#3: -
----
image#1: -
image#2: -
Result:
red: text#1/2 + desc#1 + image#1/2
blue: text#3 + desc#2 + img#1/2
As you can see from example, If you decide to use group rules, those items which stays unmarked wouldn't been considered.
But this condition is applied for the particular field only, so that's why both images were used in both groups (red & blue) but text#4 and description#3 were thrown away.
