Well, I disagree with some of those assessments of Asami. For one, yokai are absolutely amazing as a summon. They're worth hiring at 5ss in other crews, and when you can charge them off right after being summoned at + to attacks with a myriad of triggers really forces your opponent to spend resources to protect assets. All the while, while those 3 yokai summons are forcing cards, you still have a bunch of excellent hitters and support models who didn't even activate yet. Don't look over Yokai or throwing a Joro in the middle of an enemy with an extra flicker or popping off a corpse marker or two with their 3 inch MI can be a real headache.
I don't think Asami is broken, but now that there isn't nico to whine about, eyes are going to focus on the next best, which imo is Asami. I hear a lot about armor and ten thunders, but I rarely see people in tournaments or friendlies stacking armor. I think its a non issue. I typically only summon yokai, joro and the occasional Obsidian. I have used asasame against poisoners for some niche things, but not often. I don't see her summons being all that versatile, and there really not meant to be a tool kit like Sandeep, but what they do is charge immediately and forces your opponent to waste AP on them, mostly likely more AP than you spend on them. I love looking over at a near empty opponent hand and still have Emissary and Yas to activate.
