Magic The Gathering: Arena Dev Tracker
This thread was added on June 06, 2020, with posts from LeeSharpe.
The state of the game article said M20 Omniscience draft would be available from June 6-9. Also says so on the event calendar. I don't even see it counting down in the events list though.
Edit: it's up now. I guess they just forgot to put a countdown.
They have a trend of starting new events at 8:00am Pacific (About 2 hours from the time of this post).
I think they forgot to set up a countdown timer for this one, but I'm sure it'll be up.
Not "forgot", it's just when there's a lot happening (FNM @ Home, Historic Shakeup, Omniscience Draft) we don't want preview timers to crowd the "billboards" (what we call the three panels on the right of the Home scene).
Preview mode will be used for some events and not others for these reasons. It really depends on what else is happening.
