Dulling tip: whenever I'm about to lose I turn off my WiFi, and I get the message that there's no connection, so I click on retry and then force quit the whole app. Turn the WiFi back on and go in the game. It always takes me about 2-3 steps back. So not only I have a chance to redeem myself but I also know what my oponnent is going to do!

This has worked for me ALL the time since the previous dueling event, in the open dueling club, and in the current event (I'm currently on 13,didnt lose once- only played 4 times but somehow one of those times that I turned off the WiFi and force quit the app it glitches abd gave me an extra win- not complaining). I didn't lose once since I started using this!

However, I told it to my friend and that didn't work on her phone, so not sure what causes it but worth a try.
