>HOW MANY RAIDS MUST BE DONE TO GET ETERNATUS
There are many ways of interpreting this question, so if you mean:
>a) How many Eternamax Eternatus raids do I have to do for me to encounter an Eternatus after defeating it?
None anon, because Eternamax battles just grant you candy and XL Eternatus candy (xp and stardust too). No amount of battles will make an encounter appear.
>b) How many Eternamax Eternatus raids do I have to do to reach level 60 in my Go Fest Pass (the level which grants the Eternatus encounter)?
Implying that you are level 1, you need to beat 6 Eternamax battles. Each Eternamax battle gives you 100 pass points (or 10 pass levels).
>c) How many Eternamax Eternatus do I have to do to max an Eternatus?
It''s around 160 JUST to get it to level 50. If you wanna max out every max move (which you really shouldn't), you need to do around 180.

>oh and DO let me GUESS
>it CANNOT BE SENT TO THE REAL GAMES\HOME
Niantic seems pretty adamant on not letting you transfer """""unique""""" Pokémon to HOME just because. No other reason other than the fact that they didn't want you to and that's it. That's the same reason why you cannot transfer your Eternatus to the professor (thus getting rid of it) and why you can't trade it to other players.
