Hypothetically yes..but it would be very difficult. Cheating would be a problem as well. You wouldn’t be able to see the other persons hand. Also, the quality of the web-cam really does matter. You would need a very high quality web cam to pull that off, otherwise everything would be distorted. Games would also take a long time because you would have to show each other or explain the effect of each card you put down, if its not clearly visible on the web-cam. Your best bet is to go to a local tournament to play or bring the topic up subtly with one of your friends. You would be surprised, many people still are connected to this game somehow after "quitting" or secretly play.

Yes, it’s good to have a webcam above the playing field so you can see everything but yes, you can.

yea it works i duel my friend tht moved away and it works bc it shows ur opponent shuffle his deck and u can tel he isnt making up cards u can even duel me if u want bc i just started playing again and i wana try to use my old cards from 6 years ago against the newer cards

It’s quite possible, but i wouldn’t host tournaments using it. only for play testing or for fun duels.

If your using it to duel your friend, then it’s good.
You should trust your friend not to cheat and they would know what the card’s effects are.
If not, you could read it out for them.

I use webcam to duel and it’s great!
