I went from 170 to 141, so 29 hackers werde deleted infront of me ^^
Well, still no top 100, but last UC I only got to level 70-80, this time I got to 221 just thanks to 1 lucky monster draw 
(Geargant, dont even have a Vorabook to evolve him, haha!)
Well finish the xmas event you will have a vorabook
easier said than done, already lost 3 times at the first extreme level, I donāt have the right mons for a sleep lock team, my poison team failed me, as did my stun team, I think i might have a chance with the geargant team, but I already lost once with it, too X.x 75 tickets wasted already, very frustratingā¦ maybe I will just wait for another vorabook eventā¦
edit: finished the first of the 4 extreme challenges on my 4th try, but to be honest I had alot of luck, omgā¦ well, maybe there is hope to reach the vorabook
