Whilst I still can I'm going to do a Pokemon Ultra Moon Wonderlocke is anybody else still trading?

I don't really know (I remember the wonder trade timer reaching zero one time I played a few years ago, but it could have changed).

But also the Ultra versions are HARD. I tried just nuzlocking Ultra Moon once, not hardcore, no extra challenges, all items except revive allowed, and exp. share on, and somehow ended up with over half a box of Pokémon who lost and over 80 hours of playtime by the time I reached the league. Just hope you get something good against Ultra Necrozma and whatever totem Pokémon are strong against your best Pokémon (Araquanid alone contributed to 4 of the almost 20 fainted Pokémon. Over half my team had to be replaced).
