This quest is kinda hard to get. You have to use face collector and use sonya and hope for the best. If you dont get the 5 face collector's quest is done probably, unless you get sonya to proc 4 times on another minion. Also the quest does not synergize well with the other minions of this deck since the fact a lot of minions are high value and big stats. The weapon is not that good as it only has one buff. The shuffle mechanic can work with the darkness.
Probably not viable, but fun.
