I honestly love Tara.
When running her with Ressers I get access to my favorite Flesh Constructs to back up my Nothing Beast and Rotten Belles to lure opponents with their insanely high Cast stat and to turn my Nothing beast into a Yo-Yo of death and destruction.
She gets two activations a turn. one at the beginnining to buff her minions and one at the end to kill things and run schemes. Getting to do both of these every turn makes her insanely good.
Not to mention if you have a few crappy masks i your hand she is literally immune to shooting with her defensive trigger.
She does great against swarms with sympathetic echoes on her sword so Rats, Abominations, and 'anyone who takes more than one of something' everywhere beware.
She plays with Fast and Slow like nobody else. Fast Flesh Golems really hurt when they can be in perfect position or even charging turn one and a Fast Nothing Beast has 4AP per activation. Her 4 point minions can also hand out slow.
Along with time shennanigans she loves to play with the buried mechanic. Her totem and her 4 point minions are able to attack or heal buried enemies or friends respectively. This seems situational till you see that she and everything in her list can usually bury someone in some form or fashion. Masters like the dreamer who bury their own models really cant do anything without opening themselves up to disembodied attacks from every direction.
SHE GETS A + TO HER INITIATIVE!! in a game so heavily dependent on Order of activations, getting an advantage to her Initiative for a 2 SS upgrade cannot be overstated.
This may have been a fanboy speil but she has a ton of different tricks and I have never regretted putting Tara on the table. She is my pick for Favorite caster.
