Suggestion
You should include a saying like "I'm new" for new players so people dont think they are stalling/purposefully wasting others time while playing. Also one that says "nice deck" sounds better than just "Nice!"
The stall timers need adjusting, I spent 25 minutes being stalled out nonstop from someone who was losing because they would play one card and reset the timer during my turn. Then they would stall the timer out to nothing and not get a strike against them. It would be better to initiate timer counters against them instead of having to report someone.
Finally, can you code it so that Cursecloth Wrappings only triggers when you can actually use it to embalm a card in your graveyard? It gets tedious hitting skip nonstop when you cant use the card anyways but it constantly asks if you want to use it.
Thanks, and as always, You all do amazing work; the app Arena works amazing and it got me into the game big time from a guy who didnt play card games much.
