I think it is a little early to celebrate. There is a good chance MTG Arena on mobile mighr not happen the way people want it to. When you consider how much people spend on this game, its its likely that Hasbro is not going to want to give up huge profit shares to Apple or Google. Also with how shady the app store policies are now there is going to have to be huge concessions somewhere in order for MTG Arena not to go they way of Fortnight in a legal debacle. If Epic Games wins their lawsuit against Apple and Google its also a win for MTG Arena.
