GameXplain: "The Pokémon Bank and Poké Transporter is finally out in North America! Join Derrick as he walks you through the set-up and shows just how easy it all is. Plus see how the Bank interfaces with Pokémon X & Y!"
Outside of Pokemon Go, Shiny Celebi will become unobtainable when Pokemon Bank closes - until that happens, here's how to get one.
Shiny Celebi was available via movie promotion event. Dexoys is the only one you gotta worry about shiny because it can on be shiny in original gen 3 carts. That being said, they arent closing bank down. This was already stated multiple times.
Shiny Deoxys is currently exclusive to Generation 3, which means it'll become unobtainable once Pokemon Bank closes.
Pokemon Bank is presumably closing soon, and several Shiny Pokemon will become completely unobtainable afterward.
I need this!

At last, now let me go transfer my 400+ pokemon from white/black 2 to Y.
