Like others have mentioned in this thread, this will be a refreshing change from what Aztecs were classed like in the past. I was involved in the 7th ed. tourny scene back in the '90s and it seemed that every time I attended a tournament i had to fight at least one freaking Aztec army. It was so bad with them, that like many others, I would put together a specific "anti-Aztec" list to take to events that permitted one than one list. The one that worked best for me was an extremely ahistorical Medieval French army (don't ask me why I took that army to open competitions...a glutton for punishment I suppose) in which I bought up every bit of close order heavy foot with pavise that I could in big units , sheltered the knights behind these shooting-proof units and screened my flanks with my own loose order skirmishing crossbowmen, and then simply pushed the Aztecs until they had no place to evade. It even worked on occasion!

Ah memories...
