Prompts can be more specific

Something me and my friend are talking about to make it easier and more intuitive to respond to triggers on an opponents turn. When an opponent plays a card and it gives you the option to play instants and flash cards it should say something like "In response to [[Card Name]] - Play instants or flash cards"

Example: "In response to the Oath of Nissa Trigger - Play instants and flash cards"

Also pressing "done" for everything, sometimes confuses us when switching between phases, and maybe you could implement a system so that it says "Next Phase" when ending a phase instead of "done"
