I suppose one could say Crystal Wing is more "passive", whereas this is the aggressive version that hits stuff harder (and with a higher base ATK). But yeah, this was intended to be a power Synchro to deal with relevant threats (and also have a role within Level 10 Synchros; not that any of them bar maybe Leo and RDA Tyrant/Bane are doing much nowadays). Think Blue-Eyes could run this and Crystal Wing, albeit accessing the latter would require cycling another Tuner + tributing Azure-Eyes for something like Moonlight BRD / Michael or w/e Level 7 LIGHT Dragon Synchro that exists [and feels like more effort than actually worth just to make Crystal in there].
(Or you can ladder off Crystal Wing or something in this, then revive Crystal later via Gospel. That'll probably do it.)
Yeah, can't be revived, but at least Gospel still protects it in battle for the most part (bar against S39, but he's everywhere by now) and like you mentioned, by the time this goes, 2 of your opponent's resources will be gone and not really accessible. I would've considered adding the hand too, but then it'd just become a much stronger version of Trishula (well, in the sense that it triggers more, and flexible with where you can banish from / how many cards).
