7 Unowns for Celebi?

The Go Fest Celebi quest was a special quest designed for the fest, and they made Unown fairly common at the site of the fest. I strongly suspect that the regular Celebi quest will have more steps, and take several days even for hard core players. But finding 7 Unowns isn't in the cards unless they become much more common (likely still very rare, but not absurdly rare - I've never seen one in the wild, got my only one from a trade). Expect something different, and challenging, but not impossible.

Frankly, given how rare Unown is and will probably continue to be, I suspect it won't be part of the Celebi quest at all.

That quest line was made exclusively for Go Fest. God help you now if you didn't manage to finish it there.

It would be nice if they changed the moveset but sadly I find it unlikely. People will do their quests just for the dex entry and it's hard for Niantic to make any big profits off of that Thus fixing Celebi's moveset would be very low priority for them because making it better just pleases some fans but doesn't contribute much to generating revenue.

Attended Go Fest Day 2 and didn't complete the 7 Unown task. A few days later, the task changed to 7 Psychic.
