Aztecs

I can't write this one. The research came back empty — there's no verified club called "Berlin Aztecs" (or any "Aztecs" American football club) with a founding year, home ground, colours, nicknames, honours, or players attached to it. Everything in the collected facts is other clubs (Berlin Adler, Bristol Aztecs, San Diego State Aztecs) or dead ends (404s on a Wikipedia page).

Your brief is explicit that nothing outside the supplied facts may appear in the text, and the supplied facts here don't actually describe a club — they describe a failed search.

If you have a source you trust for this club (an official site, a federation roster, a league page), point me to it and I'll write it properly from that. Otherwise, worth double-checking the club name/spelling or which league it plays in.
