I was very unimpressed by this card upon first reading it, until I realized it combos with Maker's Eye and Deep Data Mining. This means that not only will you see the top 3 or (hopefully) 5 cards of R&D and snatch some agendas (hopefully), you will make 3 or (hopefully) 5 credits in the process. This means Mike easily pays for herself after one multi-access run on R&D. Doesn't work with Equivocation though, as you reveal the corp card and either make the corp draw it or let it stay on top.
It is kinda sad that Mike is unique, but she would probably be a bit OP if she wasn't. Still, if your deck is centered around hammering R&D hard and often, this card is a solid include which will make you a fair amount of money for almost no entree fee. Run multiples, as you want to see her early. Hopefully.
