Maybe you could use Parallel universe in the blessed Golden Dragons to do some more damage too.
This is going to be extraordinarily heavy on both aether and light.
How are you going to fuel Morningstars, Blessings, Golden Dragons, Miracles, Dimensional Shields, Quintessences and Parallel Universes in high enough numbers and fast enough to actually win? I have alot of experience with deck building, so I can tell you it is not a viable deack if you actually have the intention of winning.
And this assumes good draws.
