The Strength of Steel event is now live in Pokémon Go, and with it, several Collection Challenges for you to complete like This Ore That. Here, you’ll need to catch and evolve certain Pokémon before the event ends to earn every reward.
The Pokémon you have to focus on for this challenge spawn in the wild. Thankfully, each of the Collection Challenges only require you to find a handful of Pokémon. However, these ones can be complicated to track down, and many of them require certain items to evolve them in Pokémon Go. One of these Pokémon is also one of our favorites to use in the Great and Ultra Battle Leagues.
