We use the virtual dueling system known as Dueling Network here at Duel Academy in order to participate in duels.
If you need the link, just post and I'll be happy to provide it.
Once you make an account and a deck at Dueling Network, you have the option of either hosting a duel or trying to join one, as I'm sure you'll see when you get there.
I hope this helps.
