Help her accomplish this challenging task by completing the missions assigned to her!Valentina Ld is a legendary character who is only available by carrying out missions connected with her. To obtain this character, you must unlock her last mission before December 25th.
Although I've been struggling with it for days, I'm not too concerned about the Survivor mission. I'll luck out sooner or later, I've managed a few 4-win streaks so far and I managed the mission when it popped up for Gail Ld. I'd probably rather the mission was "Win 30 (40, 50, whatever) matches in Survivor mode" though, like the Deathmatch versions usually are. Upping the difficulty of all the missions overall but not having one which is so dependent on skill AND luck would probably be a way of satisfying more people.
The 2nd missions can be done VERY easily. Lots of times it isn't even about your deck, it's about how you play it. Like i said i picked up a cheap Rescue deck a while back and it got me 9 wins in a row. The deck cost me around 11.5-12k or so.
Stop complaining, if you haven't passed the mission it's because you have probably been doing something wrong or your style of play isn't working. Try changing it.
