This was definitely the hardest shiny I've ever had to catch so far. I had Makomo (Named after Fennel's jp name XD) in the lead, who was my syncher, and thought I'd try using a Quick Ball first before anything else. But of course, that didn't work |D. Kyurem KO'd Munna straightaway, so I sent in my Darkrai from the 2012 Wifi Event (Wish I could have my own, shiny one T_T), to use Dark Void and put it to sleep...except he woke up straight away XD. Then I switched in Daisuke, set up with Swords Dance and False Swiped him down to 1 HP.
I threw tons of Ultra Balls and Dusk Balls, but he WOULD.NOT.STAY.IN.ANYTHING. The ball wouldn't even shake once
more than half of the time!
In the end, I was scared of him ending up using Struggle, so I caved and used my Master Ball.
His IVs are:
Sp Att- 28 (Woot!)
Sp Def- 20
Spd- 27 (Yesss)
I'm so happy I finally got him, and the perfect Nature and great IVs were an extra bonus <3 the shiny colours are even more beautiful on the actual game screen. I named him Kyuwuji, which is a combo of Kyurem and Wuji, the "absence" of Yin and Yang.
