The recent tiering changesDO NOT come into effect until Round 2 of the UU, RU and NU opens.
This means that for Round 1 of these tournaments you must play the tiers as they were on July 8th. So once the servers are updated you should play these games in the OU tier (this is to simulate the old metas, you can't bring a Landorus-T to your UU game just because it was played in OU)

The recent actually correct tiering changesDO NOT come into effect for round 2 of the UU Open. The metagame played for round 2 will be the same as the one played for round 1.
Gastrodon, Gliscor and Serperior rose to OU, while Amoonguss, Diancie-Mega, Mamoswine and Venusaur-Mega dropped down to UU. To make it easier on you all, here's a quick summary of what is and isn't allowed for round 2 of the UU Open:
Because Gastrodon, Gliscor and Serperior are moving to OU even though they're still allowed in round 2 of the UU Open, we ask of you to play your round 2 games in the Gen 7 OU format in order to still be able to use the aforementioned Pokemon. If you're caught using Pokemon that aren't allowed in your UU Open games, you will be disqualified from the tournament.
I forgot to mention this last night, but the RU Open and NU Open games should also be played in the Gen 7 OU format due to Gastrodon rising all the way up to OU. Because Gastrodon is still allowed in round 1 of RU Open and NU Open, please play your round 1 games in the Gen 7 OU format if you haven't played your round 1 games yet!
