I threw this deck together a few days before heading to Italy, and as such, brought it to the tournament completely untested. As such, only after the game against Cobalt in round 1 did I discover the lines you can and should take with it, and once you do, you can runners that are currently strong in a lock that is very hard to get out of.
The main combo here, similar to Augustus' NEH in standard, is to overwhelm the runner with an onslaught of assets that is hard to deal with using Warm Reception, and bouncing key econ resources using Working Prototype. This plan is supported by Ablative Barrier, the main target for derezzes, and The Powers That Be, that together can provide an insane amount of recursion.
The evening before the tournament, I had the 'epiphany' (heh) to also include Reversed Accounts, and really, this deck should have a second one instead of the single Behold!. It is an amazing target after a Stoke the Embers score, especially since you can first recur it using The Powers That Be and then place an advancement counter on it. It is also a fantastic target for The Holo Man; being able to spend 4c and two clicks to delete 12c from the runner is just so very rude.
As a general guideline for playing this deck: Use your ID ability with impunity. When runner gives you counters, makes them regret that; every counter is a click for a draw and an install in one, coupled with valuable knowledge for scoring plays.
Finally, another change you should probably make is to swap the Seraph for a third VSA, as your ice does not do well against a Physarum Entangler suite, the tag threat that VSA provides is quite useful.
