Perdita is considered a easy Master to play,beacause she has DF and Wp7.
Obviously she isn't easy,beacause she has only 10 wound and no defensive trigger against Ca or Mi.
Actually Papa Loco and Santiago aren't competitive, especially Papa Loco.
In my 2 lasts game I play Nino but she always died without do nothing, against Gremlins is died the first turn on the first activation...
Good models with her are Abuela (but I never run she with her),Francisco(obligatory),the nephilim, and 2 Monster Hunter.
On the firsts 2-3 turn you need absolutely Francisco that put Df9 and wp 9 on Perdita,then I tend to fire heavy on first turn only if there is a chance to put pression on enemy Master or if I'm certain to kill a model,you need a good hand to do this beacause her damage is not very high wit only 2 of minimum.
The Problem of Perdita is the very low caches you need to build a crew with at least 8 models and at least 5 soul stone...
Obligatory upgrade are "fastest drawn in Malifaux" and "Trick Shooting", "Witched Bullet " on card is very good but every time (EVERY TIME,ALWAYS) that I buy it ,When I use it I flip the black joker, so I've stopped to buy it.
