They were:
1. By killing and absorbing the cores (like how Shedinja and Nidoran did in the earlier chapters)
2. Improving the move mastery relating to the specific typing.
3. Elemental gems.
Elemental gems were by far the easiest way to improve core mastery. The better the quality of the gems, the faster it would be. Since the league had gifted Axel with the highest quality of elemental gems for Shedinja, 1 of them would be enough.
But it would take a couple of months for the core % to be filled up.
So, Axel was doing all the 3 things to improve Shedinja's core mastery.
Axel had been thinking a lot about the new world he had been in for 13 years. At first, he thought that the world of Pokemon and anime or games were very similar. But he knew that it was wrong now. So, he decided to change his thinking to start a new one.
The first thing that came to his mind was 'Gravity' learned by Shedinja. Shedinja was a bug/ghost type Pokemon and normally it never learned gravity. So, why did his Shedinja learn it? At first, he thought that maybe one of the parents of Shedinja was a Physic type Pokemon but now he thought there was a different answer.
The answer was 'Hidden Power'. As per anime, the type of hidden power differs from every Pokemon and normally, Shedinja's hidden power was a fighting type. But what if, every other Shedinja have different types of Hidden power?
What if his Shedinja had Physic power? If that were true then it would be awesome. Then Axel could also train Shedinja in physic moves.
Axel had never come across anything relating to this move so he had never given it a serious thought. Anyway, right now he was in a forest. He was planning to research it when he reach the next town.
Walking through the forest was very scary at the beginning. But now he was used to it. It was boring now. It would be a miracle if he would meet any trainers. He had only met 9 of them so far. He had battled all of them and won all the battles. He mostly used Beedrill cause it would still need some fighting experiences.
Beedrill was very far from rare ranked. It had been a month since their journey and Axel expected that it would still need a month and a half to reach it. He was not so hopeful that Beedrill would reach rare ranked when he reach Pewter City.

Axel was also thinking about Bulbasaur. There was only 1 reason he chose to have Bulbasaur and it was to make Bulbasaur as powerful as Hashirama Senju.
Hashirama Senju was known as the God of shinobi. He had many abilities and some of them were:
1. Wood clones
2. Can make Wood dragons
3. Heal instantly in the blink of any eye
4. Can create a forest in an instant
5. And absorb the life energy of opponents.
If Bulbasaur could do all these 5 things then it would be the most powerful Bulbasaur in the history of the Pokemon world.
Right now, Bulbasaur didn't have any healing moves like Synthesis and Giga Drain but he thought to teach it now for a good foundation. As per the wood clones, if he could evolve 'Substitute' to a higher level, maybe Bulbasaur would be capable of doing it.
Bulbasaur had a lot of moves to learn and master. It was now time for it to start its training seriously. The first 2 moves that Axel wanted Bulbasaur to learn were 'Sunny day' and 'Synthesis'
Axel wanted it to be proficient in healing itself as one of the most broken abilities of Hashirama was self-healing. He could heal in a blink of an eye. The Power of Synthesis increases in sunny weather. Bulbasaur was tasked by Axel to practice those moves 2 hours a day for the past month.
Other time was spent on practicing 'Vine whip', 'Substitute', 'Sludge', 'Razor leaf' and 'Tackle'.
Bulbasaur had improved a lot during this past month. It was a hardworking kid. Bulbasaur was now the second weakest in Axel's team after Magikarp. So, when he heard that Magikarp would evolve into a powerful Gyarados after a couple of months it didn't want to be left behind.
Axel and the team had their rest and now were going to resume their journey. Just as they walked for a couple of minutes, Axel noticed a young trainer. Just as Axel saw the trainer, he could feel the rage of Shedinja in his shadow. Axel then knew who that trainer was.
"It has been a long time Axel.", said the young trainer
"I can't believe that you still remember my name"
"I won't forget my first defeat"
"Yeah, I still remember that you owe me 1000 Poke dollars."
"Well, sorry about that. Why don't I win you by battling right now and make it even?"
"You won't. But you can try, Bruno."
