Ran the original incarnation of this list again twice last night. I wanted to see if I could handle a Riekann bomber wing without introducing the squadrons, and I'm very pleased to report that I won both times. They key is getting the timing down. Both my opponent and I learned from our first go, so approached things a little differently the second time. I managed to time it perfectly, such that my first Slicer hit Yavaris the turn before I would have seen the first double tap. The next turn, both ISDs moved into position, followed by a second slice on Yavaris. I popped Yavaris and a couple transports, plus got the final slice on zombie Yavaris.
This can work. It's not foolproof... but it's a list I've found success with that runs NO SQUADRONS, and that makes me happy.
