Ok great. Just a note that offensive niches usually aren't as defined. Let's take stonjourner. A rock-type lategame cleaner that can outspeed SG Magearna and hit steels. No one looks at a team and says "I need a rock type late game cleaner that can outspeed shift gear magearna and break ferrothorn." Of course, it's perfectly viable to build around them, but that's not what makes something "meta".
