Hi zarel, I have an interesting idea for a new meta called power trick which basically involves defences and offenses being swapped all of the time. Sorry to bother you but I didn't know who to suggest it to, it would be interesting with like skarmory being offensive and alakazam being a special wall :)

However, some similar ideas already exist, if I recall correctly.
