This is nothing more than a 5th level version of Counterspell, that doesn't use a spell slot.
Well Shining Counterspell has more to it considering Counterspell doesn't deal damage. Also Alustriel makes a D20 test as opposed to the target and it's not subject to any spellcasting limit nor it is Counterspellable. More importantly, it's not just usable against a spell with Verbal, Somatic, or Material components.
