List of models i like with Sonnia is
Witchling Stalkers - Remove conditions, hand out burning, great melee attack. Our best minion overall imo.
Malifaux Child - (Double Flame Pillars is a thing)
Watcher(s) - These are our best scheme models by far.
Francisco - Just all around superstar with El Mayor and usually becomes the focus of my opponents attention
Pathfinder - For Squatters rights and generally i feel this a model an opponent must remove or the game will start going downhill for them in the later turns/
Judge - Another all round henchmen, this guy is just a work horse.
