>>50839782There'll always be a lowest tier where >40% of Pokemon reside. Smogon could make another 5 - 6 tiers below ZU, but there's a couple of issues with that:
1. Low tiers already see very little usage. NU and PU have like 3 matches going on at any one time compared to OU's 80 - 120.
2. What can possibly be lower than Zero Used?
