I'm using this deck to farm Kaiba. It is so consistent, you can say about 95%! Lately, I have farmed him a lot, and today, I farmed him five times, however, I didn't get any single SR card! Why is the drop rate very bad? Any help or suggestion guys!?
I usually exit game if the farm yield is unfavourable. Open, farm, exit, repeat, until I get an SR drop. After that, I usually will get SR drops continuously as long as I don't exit the game. Not 100% of the time, but pretty frequent.
