With only Norman and Raquel, it seems like UR Devs gave up on this ability combo.
But since there's a group of missions that require you to Lose 250 Pillz by Backlash, you'd think they'd offer more than 2 characters to make that happen.
Just got to wait. They might release more in the future.
I think it's really just cause backlash -life is more effective than -pillz in terms of what's equal given how backlash cards have higher stats than normal cards.
