Please allow us to turn off animations. I want to use an older computer to run MTG arena, but it cannot handle the excessive animations, even at the lowest graphic settings.

There is probably some sort of marketing or focus group reason that exists to force players to see animations, because Hasbro thinks that it will foster interest. Or, perhaps employees such as animators are hesitant to allow this due to fears of becoming redundant and losing their jobs. However, this puts hardship upon the users and create a nuisance, please reconsider your course of action.
