So someone just ragequit against me because their Marshadow didn't have Sash, and they thought it would because I guess it's always been in a lead spot before now so they thought Sash was the only item it could get. Considering we now have this guide that explains set generation in Gen 8 Rands, I feel like sticking this at the top of the battle log like we do in SSB4 could be a nice way to make rands more newcomer-friendly in an unobtrusive manner. Of course, this matters less in this scenario because the opponent could have just checked their Pokémon's set, but if I had the Marshadow he would have been playing around it assuming it's sashed the entire battle.
Something like here:
Similarly to there, you can also include the /randbats command in the box to remind people that that exists, and could perhaps have an announcement pointing out the existence of that command in oldgen rands too.
