Can you derank in arena?

so I’m wondering if you can de rank in arena, like down from plat 1 to gold 6…ive lost a handful of games and don’t seem to go down any except from within the same teir

You can’t de rank. If you just became gold, you can’t go to or back to silver

But you can derank from Gold 6 to Gold 5, 4, 3, 2, 1 if you lose enough. Just not an entire rank.

what about onyx. Can you de rank in that?
