It's my first time to make it to round 6 and I thought I could make it to the next round after winning the first round but I was mistaking. Anyway, it was really a difficult match but it is competitive and exciting.
Another thing is that I open up a Gold Naga Windmaster which is a good monster card that could help suppressed those enemy range-attack monsters. Luckily today, 611 DEC is being acquired also.
I was able to make it to Diamond I but recently dropped after I'm having a hard time completing my daily quest.
