I hate that I hate this card. I love Tabitha as a character and I am always on the lookout for good Aggression allies, but unfortunately this isn't it. Her main issue is she gets value for you waiting. But... this is Aggression, an Aspect that almost forces you to rush. Sure, she'd be great if you could use her with Uncanny X-Force to thwart with her every turn while you wait for that build up, except that's not legal because there's no X-Force character like Cyclops that will let you run an Aggression ally in a Leadership deck. Tabitha is pulling herself in two different directions. Maybe if she was cheaper, but for 3 cost you are getting a 1 point action and a chump block, or having her do NOTHING for multiple turns and then chump blocking at the very end?
I am not sure what the design intent was for this was within the X-Force cycle, but Tabitha deserved better.
