I found it! Thanks so much for the help!

There is an abandoned forum that has an invalid discord invite and this is the most recent post about discord. I'm sorry for going kinda off topic but are only certain people able to join the discord? I can't find an invite to the tanki online discord that works.

I think when an Isida from each team attack each other there should be the Harry Potter effect when Harry and You Know Who attacked each other. Just a thought. :)
