I keep hearing this rumor and I want to share it with you guys, too.
There seems to be a data miner (I don’t know who) who seems to have always been right with his leaks. He now has leaked Alakazam Raid Day, which will be pretty much like Gengar Raid Day. According to his leaks, Alakazam Raid Day will take place on April 7th usual CD time (Treecko CD excluded)
Europe, the Middle East, Africa, and India: Apr. 7 2019, from 10:00 a.m. to 1:00 p.m. UTC (GMT +0)
The Americas and Greenland: Apr. 7, 2019, from 11:00 a.m. to 2:00 p.m. PST (GMT −8)
Asia-Pacific: Apr. 7, 2019, from 12:00 p.m. to 3:00 p.m. JST (GMT +9)
and shiny Abra will be added to the game immediately when the Alakazam Raid Day has come to an end.
Do also note you’ll be given five free Raid Passes during the event time in your region.
Now what’s your opinion on this, in case this is true?
