Not sure what screenshots would help but every time I turn on gate farming the bot just ends turn rather than playing any cards
Have a look at the feature list. Does it say “play cards” anywhere? 
To use the gatefarm feature you will have to use GameGuardian or a modded apk (although we recommend GameGuardian).
That way you instantly win against the duelists. Please have a look at the tutorial section on how to set up GG
