PSA Showdowns CAN occur at a Battlefield you have already scored this turn
This has come up multiple times today on RiftAtlas, so I thought I would share it here so everyone is aware. It is particularly important for games involving Akali.
In this scenario, I had scored both Battlefields this turn. Just before the image above, I had attacked Hall of Legends with Twilight Reveler, which was defended by Tideturner. I used Twilight Reveler to ready Stellacorn Herder, who was at Abandoned Hall, and then moved them home. This meant that I now no longer controlled Abandoned Hall.
Afterwards, I moved Jhin into Abandoned Hall. Because I now no longer controlled it, a showdown should have occurred, which would then allow me to do Akali shenanigans (e.g. run Jhin home ready etc). EDIT: I'm just adding that I am very aware that you do not score/conquer a second time. It just creates a showdown, which is the important part.
It is an unusual interaction, but it is a really important one to be aware of when piloting Akali. Unfortunately, OLIGEH here didn't know that, claimed they were a judge and I was wasting their time, and decided to leave before getting 2-0d comfortably.
As I said, this has come up multiple times today, so thought I would share this here so that people are aware of a useful trick and also so if I play against one of you later online, you are aware of it and don't decide to yell at me and leave the game. :P
