Ok. I don't know it if this is a dumb question, but are theme teams that have a team that isn't completely that theme allowed in RMT? For example, if I made a Team called Flying Spam for NU that had 3 viable flying types, and the other 3 Pokemon are Pokemon that are viable and support the flying types. Would those kind of teams be allowed, or does it break the rules of no theme teams?
The discriminating factor is whether you can honestly say you're playing to win. If you think 'flying spam' is a good idea in NU, then sure, go for it.
By contrast, this team of monkeys is a joke. There is no way that restricting yourself to only those Pokemon creates an advantage. It can't be taken seriously, so we remove it.
Every team is thematic in some way. Just be reasonable.
