Mega Lucario challenge is back on Pokémon Shuffle

The Mega Lucario stage is back for the third time in Pokémon Shuffle and will grant you yet another chance at obtaining a Lucarionite for your Lucario, which cannot be obtained by normal means.

If you already have a Lucarionite from one of the previous events, you will be awarded two Jewels. If you have yet to win, however, you’ll have to be ranked as one of the top 15k in Europe, 30k in North America, and 60k in Japan to earn yourself a Lucario’s Mega Stone.

As usual, be sure to hit Check In to update your game and gain access to this event. You have until July 20th to enter.
