Yes, the Ultra Beasts are allowed

>B-But the UB are broken!
No they are not, stop being a reactionary dummy. Stop thinking things are broken just because they have one very good stat. Notice how all their other stats are below or very below average. They don't even reach 580 BST.

>B-But Mega Mom and Mega Mence!
Megas are not allowed this year so that Z-Crystals and Moves can be shilled properly.

>W-What's good this year then?
Things that can be expected to be good are things that have always been good like Garchomp, Salamence, Gengar, etc. Of the new Pokemon? The most prominent are obviously the Tapus as they all have excellent typings, BST an abilities. Expect them to see them very often and to pack something agaisnt them.

Here's a few pages that have small compilations of interesting or good Pokemon or usual VGC staples.

>W-When's the earliest official event for this format?
It'll be on London between the 9 and 11 of February. It'll be the first of many International Championships.

Yes, TCPi thought it was a good idea to make a Nat-levels tourney as the first tourney of the format with less than a month for a meta to establish and for people to play the game and to breed their teams.
