I put up another leader strategy guide on my blog a week ago (sorry for being late about posting it here). This guide is a vanilla civ that was requested by one of my supporters, and covers Montezuma of the Aztec: http://www.megabearsfan.net/post/2020/02/02/Civilization-VI-strategy-Montezuma-of-Aztec.aspx Even though Montezuma is a vanilla leader, this guide is up to date with Gathering Storm rules. Montezuma is built to be a highly aggressive leader. The Eagle Warrior can capture defeated enemy units as Builders, which can then spend charges to speed up the production of districts. This can dramatically speed up the development of Aztec infrastructure, without necessarily having to actually conquer the other civs' cities. Spam Eagle Warriors (which are ancient and cost 0 maintenance) early in the game using Agoge, and check the combat odds widget in the bottom corner to make sure that you are dealing the killing blow with an Eagle Warrior. Every unit that you kill with a unit that isn't an Eagle Warrior is essentially surrendering a chance at a free Builder! The odds of capturing the unit seems to be determined by the strength of the defeated unit. Odds are displayed in the combat odds widget if the combat is likely to kill the defending unit, and they range from abut 70% against Slingers and Warriors, and degrade to 0% for Musketmen. Even after the Eagle Warrior becomes obsolete, Aztec can still mass produce Builders (using a Builder-boosting policy, ideally) in their high-production cities, and then use them to rush the production of districts in newer or less-productive cities (effectively shifting production around within their empire). This makes it much more viable for Aztecs to found new mid or late-game cities. Sadly, you can't spend builder charges to rush the repair of a pillaged district (e.g. districts you pillaged before capturing a city). Don't use all your Builders to rush districts though. You should probably keep a few Builders with 1 charge remaining in case you need to repair improvements pillaged by enemies or damaged by disasters. Montezuma's ability also gives him additional amenity from luxuries within his empire, and each distinct luxury in his empire grants a +1 combat bonus to ALL military units (land, sea, and air). Even though the luxury is improved within Aztec lands, if you trade away the last copy of a luxury, you lose the bonus. You also don't gain the combat bonus for trading for a luxury that you don't already posses. So no reason to be diplomatic or to trade excess luxuries for ones you don't have. Try to prioritize settling (or conquering) near luxuries that you don't already possess, but don't spread yourself too thin, or else you may have trouble with loyalty, or might leave yourself vulnerable to invasion. The full guide on the blog includes more detailed tips and strategies, as well as some tips for playing against Montezuma's Aztec. I always welcome feedback, so if I missed any good strategies or tactics for Aztec, please share your ideas in this thread or in the comments on the blog. Happy Civ'ing!
