I hope this doesn't offend you, but my english teacher would draw and quarter you for this post. She's such a grammar nazi...cross tier teams are perfectly acceptable on smogon and simulators you just can't have pokemon from higher tiers on your team lets say in a uu battle you have something from ou that isn't acceptable but you can use anyone from the lower tiers it sounds like you were playing with people who didn't understand the rules and now your complaining about yours and their lack of understanding of how the tiers work and the reasons for banning certain pokemon
Yes, that is what I'm saying. Smogon makes a rule. Someone reads a rule. He/She tells all his/her friends the rule. The 'telephone' game starts. Before long, the Smogon rule is just a 'rule' that everyone 'knows'. Additionally, their example movesets, in my opinion, pidgeonhole pokes into certain positions, and then they are defined as such. I'm sure that this will just start another wave of people telling me that I'm wrong, but I don't think any Pokemon should be banned for any reason because they all have weaknesses.
Also, where are these simulators that everyone keeps talking about?
