The Ferrum League is the main part of the game. In this, you have to battle through various leagues, defeating trainers to increase your rtank. This is the story mode of the game and features a variety of trainers as well as the mysterious story of Shadow Mewtwo.

There are multiple ranks to play through and they unlock as you progress through them all.

The League Match is the bulk of this mode. In this mode, you go through 5 battles against other trainers in order to rank up. Whether you win or lose is unimportant but your overall rank in the league increases based on your progress. Each league has got a specific number of characters within that you share the rankings with, but you do not need to face them all

Once you have reached the top 8 in League Match, you will be able to qualify for the Tournament. This is a Knockout competition and will go through a tournament bracket until you emerge triumphant. As such, only three battles will be in place in this mode as you go through and become champion

When you win the Tournament, you will get a variety of prizes.

Once you have beaten the Tournament, you can then move up to the next rank. However, to do so you need to defeat the leader of the league in a battle. These leaders are the strongest opponents in each league so require a lot of skill compared to previous matches. Once defeated, you will get prizes such as more Support Pokémon as well as move up to the next rank. In the Iron League, this is the final match of the story

Free Battle is simply the mode that has you play against a random character from the league for a quick match which doesn't impact your record or ranking in the league
