Where do you live?

You missed 3 potential things of note:

1. Alolan Starters: I wouldn't worry about this one. They're going to be widely available once V4 comes around (*cough cough* maybe never *Cough cough*), and you can easily trade for them. 

2. Deoxys Form Event: This event was boarderline impossible. You can see in the Pokedex yourself that almost no one got them. 

3. Discord Cosmog Giveaway: This isn't really an event, but it's something important for you to know. Cosmogs are given away each hour on the Pokemon Vortex Discord. You can see an in depth details on them on the Wiki Page of Pokemon Vortex
