Stewart looks great. He is a solid enabler. Some of his stats are weak, but most important is his 0-upkeep 1-influence. And the ability, of course.
As for Ms. Lash, holy hell, she's pricey! Probably prohibitively so for most decks, unless we see a shift in tempo or cost structure. But she is badass! Is Sloane turning into the superfriends faction? Maybe we'll get some use out of "A Piece of the Action" after all!
