I started Malifaux this summer when a number of people at my local club started playing.
So far I am loving it, it is a nice change from W40k. The alternative turns is a great feature for me. The card mechanic is fun, it adds some resource management to the game.
I enjoy the smaller scale as I can spend more time painting each model. Its also easier to transport.
So far I just play Guild which I have all the models for so far. I have also just started a Dreamer crew but have not used them yet.
The guild are the most straight forward faction I think, each model is pretty powerful but they are slow and cant heal or summon new units very easily. They are very good at range which makes up for this.
I mostly play Sonnia Criid who is good at magic and great against other casters.
The neverborn have some awesome models and great masters. Which one you thinking of trying?
Lilith is a melee monster and very fast, they are few models which can stand up to her in a one on one. Her crew are all about speed, they are good at hit and run attacks and grabbing objectives.
I have not played against Pandora and have only played against zorida once but I have heard they are good masters.
You can check out the wyrd forum neverborn section to get a idea of how they play.
Here is a picture of some of my guild. Sonnia Criid,Witchling stalkers and Samuel.
