This is definitely a combo card or a situational ice. It's definitely not a snap rez: you don't use this in a conventional way to reliably tax the runner over time. If you're thinking about value exchanges vs popular breakers, it's pretty bad.
Instead you want to leverage the "When you rez" ability for a time when its impact will be heightened because of the situation (preventing an Apocalypse run or Deep Dive, for example). Think of it like Anemone or Formicary.
At other times, it could be good depending on synergies with other impactful cards, by screwing up the click math on Manegarm Skunkworks or Mr. Hendrik or Thule Subsea: Safety Below, as Diogene notes above, or even Tempus, or robbing that important click needed to click through a Fairchild 3.0, for the few days before Flashpoint rotates.
Hard to say if it can pull its weight in a committed harmonic ice suite, but maybe consider it if you are looking for ways to tax or surprise runners for clicks, and you can afford to rez ice situationally and still advance your win conditions.
Also worth mentioning that a runner like Nyusha "Sable" Sintashta: Symphonic Prodigy, who often has plenty of clicks, is particularly well-suited to deal with this ice.

If you wanna personally thank them, then talk to them instead of posting ice walls of text here. Also, while you're at it, tell them to get a better name.
