Welcome to the SV Battle Stadium Singles Viability Rankings. By this point the ruleset has moved on from the current ruleset and officially ended on September 30th 2023, though the sudden drop of the new Pokemon introduced in the first DLC effectively ended the ruleset a few weeks early. While the active thread has moved on from this ruleset, here is where we ended up on Regulation D before the meta transition. This thread won't be actively updated but if you look back here in the future and see that maybe we were off-base with some placements, feel free to comment! Otherwise this list is mostly here for archival purposes.
