I would see how it works before condemning it, it could potentially be fun (you combine unit cards, generals cars, tactics cards, culture and institutions cards into "decks" which are called armies). My main problem with this setup would be this abstracted, too arcadey feeling which was the plague of civ6, armies not having army vibe but some abstract card vibe. I already struggle with how in 1UPT you de facto don't have decisive battles of history, just myriads of skirmishes.
