The early Pueblo never saw horses. Giving them horses would be weird. If anything, they’d be a defensive civ that employs an extensive number of infantry units.
Also, including the Comanche would be weird as ■■■■, the Comanche have only existed for about 250 years, if that. If you want a plains Native American civ, the Seven Fires would be the best choice - that’d be the Lakota, Dakhota, and Dakota, which have existed as their own distinct nation since at least the early 1500’s, and likely much earlier than that.
I have a concept drawn up for the Seven Fires, if you’re interested.
