Where can I play Dominion?

Hey all, it's been years since I posted on the actual website. I used to be a VERY avid League player since the early days, but when Dominion was released I switched to it and pretty much played entirely just Dominion. I loved the fast paced, quick, fun brawls I could have without worrying too much. I guess I went full casual by that point.

Then I stopped playing for like 3 years. I came back a month ago and played some more Dominion and it was just as great as I remember (long queue though for some reason). I just logged in again today and I can't find it anywhere? Was it moved to a custom game or what happened? Thank you. I couldn't find anything about this but to be honest I don't even know how to navigate this site, it's changed so much.
