This week was too easy versus the others. To be honest, the only difficult part (for some) would have been earn a candy walking your buddy. If you used Wailmer (PUCKY TO THE RESCUE) or a similar 1k/candy Pokemon at that point, all you needed was to walk the 1 km. Maybe you had a buddy lined up for less than 1k of walking or you could have thrown a Poffin at your buddy if you were more than 1/2 way to a candy. I walked my Reshiram 1.2 km (or so) to get the candy since I was still working it for Best Buddy (which I did earlier this week).
The Elite Challenge was more time consuming than difficult. 30 gifts took 2 days since I don’t have a lot of stops at home. 30 berries was more of a pain to remember to use them than anything. 30 hearts was easy enough, just berry and time consuming.
At least there were no evolve or power up tasks!
