I'm sorry but can there be other verified and reliable farming decks, other than Yubel farms? Unless someone can recommend a method for characters other than Yubel to use it? I'm coming from the standpoint of these events being great for farming skills too, and when your Yubel's skills are all done you'd want to grow other characters too.
Plus what happens when the ideal decks can't be used in the world these events appear in, like the event Yami that roams in DSOD now?
Just sayin'
depends on what is your goal? if you want to reach 10,000+ score and 500,000+ Event Points.. withour RA and Yubel it's not possible. Other decks will not give u 10,000+ score. But if you think that 5000-8000 score is ok, there are many decks like Silent Magician, Amazoness, exodia, destiny board with 100% win ratio.
