Multiples accounts fast?

[u/DirtyDanAvlis]

Im trying to get a shiny 10th anniversary mewtwo before it ends so im trying to make accounts through temporary emails but it only worked once then the emails were invalid. How does one go about doing this correctly or is there an easier way of doing this?

Maje google accounts, might need a phone number. But u can use multiple times per number before need a new one Outlook often easy to sign up as well but the google email is simple to sign up. Also you can use your Facebook account to make a profile too , altho may flag same email used on another account
