Looking for a challenge? Participate in Pokemon Sun/Moon’s upcoming Weakness Cup competition, which will be taking place online on July 20, 2017, 00:00 UT to July 30 23:59 UTC.

In the Weakness Cup competition, trainers will have to assemble a team from a limited list of Pokemon which are weak to at least 5 types in battle. All Pokemon will have to fight in Single Battles – one wrong move could be extremely fatal.

Pokemon brought in via Poke Transporter are permitted to enter the competition. For the duration of the match, all Pokemon will be set to Level 50. There’s a limit of 15 matches for every trainer each day.

Trainers who participate in at least 3 different matches will earn four Mega Stones – Ampharosite, Altarianite, Latiosite, and Latiasite.
