So I just got access to the anomalies and am running around trying to catch a bunch of Legends, and while it's doable with Ultra Balls, especially when you can drop them to 1hp and sleep/para them.
I would like the option of timer balls, considering it's taken over 150 Ultra Ball, just to catch 3 of the legends so far...
Is there a place where you can currently find/buy some timer balls?
