My first impression was that this puzzle had so many — too many — diagonals of black squares rising from left to right. Kvetching alert! Those middle diagonals break up the solving flow! All those pyramid blocks around the perimeter felt like cheating to this constructor (they make a grid way too easy to fill)! Forty-two total black squares is too many!

Boy, did I feel silly when I realized that the black squares were thematic. I didn't catch on to the theme until very late, and I loved when the switch finally flipped on. STAIRCASE WIT, ESCALATOR CLAUSE, ON THE UP AND UP made for a simple concept, but the black square patterns — every single one of them rising diagonally — made for an elegant touch.
Excellent craftsmanship, very little crossword glue anywhere. Some people may complain about SCRY, but I think it's a fair word, even for more novice solvers. Then again, I do love sci-fi and fantasy novels ... if you haven't read the Bartimaeus Trilogy by Jonathan Stroud, you're missing out on some awesome SCRYing! (More importantly, the crossing answers are all gettable; even REMY Martin ought to be at least familiar).
Great BANK clue, playing on Penn and Teller. How have I never realized that a BANK has both pens and tellers? Love those sorts of connections.
The puzzle did play hard for me, what with less common vocabulary such as TRICORN, ANTEHALL, ASYLA (that really is the plural of "asylum"!) to go with SCRY. I happened to be familiar with all of them, but I'd understand if these answers left an odd taste in solvers' mouths — I think it's better to stick to just one or two of these potentially head-scratching words.
But with great bonuses like COSPLAY (I happen to look a great deal like EVIL Spock to begin with), EVIL EYE, CHALLAH, ICE CUBE TRAY, I thought Mike executed well on his grid on the whole.
Great visual with all those STAIRSTEPS in black squares. I didn't immediately know what STAIRCASE WIT was, but even then, I liked learning the term. Neat idea, an inability to come up with the perfect comeback until one is at the bottom of the stairs and needs to rush back up to use it.
