Not until after beta is over, at the very least.

For anybody who wants to play arena on ipad - I really recommend Chrome Remote Desktop. It does works quite fine.

That's amazing man! but does the iPad overheat?

My ipad air2 doesn’t heat at all.

Although you have to note, that it's not as fluent as computer/ ipad duels due to streaming your own desktop. Still, I play on ipad everyday due to the convenience.

Sounds convenient but man... how do you play on something so small?
I'm using a 22 inch HDMI tv as my monitor and sometimes look over at the 32 inch HDMI tv and think... yah, that's more like the proper size.
LoL
Just getting old I guess.
Get off my lawn!

rust never sleeps...

And since you gave me the perfect, in the know opening... off topic...
Yes, that's me stage left on the Strat and harmonicas.

An interesting observation is, that I’m more concentrated/make less mistakes, when I play on my ipad. I don’t know if it’s due to the fact that the game is smaller, works a bit slower due to stream or just comfortability of the ipad.

Edited the main post. Maybe someone else will be looking for info, how to run Arena on a mobile device.

I routinely play Magic Arena on a 7 inch screen on my GPD

I routinely think of you in the shower.

I tried playing arena on my phone and it's playable, but if your wifi temporarily fails for some reason, with arena's timer, your gonna get screwed.
I've lost a couple of games when I had lethal or good chances of winning, due to time-outs at crucial moments.
Still, it works pretty well with a touch screen and screen size isn't really an issue for me.
