Por qué no puedo formar un equipo en Dragon Haven.
Hello! Welcome to Smogon! I can't say for sure but imagine you're using the wrong version of Dragon Heaven. Double check and make sure you're using
the right server (linked here). There's an older DH and a newer one, the older one is pretty outdated and teams don't properly show up without a different link. Fair warning that the newer DH that I just sent will take a bit of time to load, so you will need to be patient with it. I also do speak a little bit of Spanish, so I do understand the question, but this is an English-only subforum and future posts that are not spoken in English will be deleted.
Thank you! Please let me know if you have other concerns!
