Alright, the
usage-based tier update for July is out and this is how it impacts your Grand Slam run:
UU Open
- No changes;
UU quickbanned both Mimikyu and Pinsir-Mega with the intention to test them properly following the Altaria-Mega test
RU Open
- Feraligatr moved up to UU and alongside the
recently banned Linoone won't be allowed from Round 2 onwards
- If you haven't played your Round 1 games for RU Open yet, please use the
Gen 7 OU format to do so; read the post above this one as well
- You can use the
Gen 7 RU format again for Round 2 onwards
NU Open
- No changes
PU Open
- Mesprit moved up to NU and it
won't be allowed from Round 3 onwards
- Ferroseed dropped down to PU and
will be allowed from Round 3 onwards
- Mesprit is still allowed for Round 2, so please do so in the
Gen 7 NU format in order to still be able to use Mesprit
- You can use the
Gen 7 PU format again for Round 3 onwards
LC Open
- No changes
Round 2 of PU Open was posted before the usage-based tier update was posted, so that's why the changes for PU Open won't go into effect until Round 3.
