This is not the native Pokémon world that the world knows.
Here, from the first gym challenge of a novice trainer to the pinnacle showdown of the alliance championship, all official competition battles are engraved with an iron rule - each Pokémon can only bring four skills to participate.
For a long time, family trainers with inherited resources have relied on skill scrolls and secret teachings accumulated over generations to allow their Pokémon to master more than ten or even dozens of skills, crushing civilian trainers in battles. Pokémon from civilian trainers can often only learn basic skills. Even if they are extremely talented, they cannot match the absolute gap in the number and diversity of skills. Countless people's trainer dreams are shattered in the face of the resource gap, and regional balance is almost collapsing.
In order to curb the power of the family and protect the living space of civilian trainers, the alliance united with authoritative forces from various places to jointly issue the "Four Skills Restriction Order". The rules are clear: Except for daily training, in all official battles, the Pokémon's usable skills must be limited to four. Violators will have their results cancelled, or even be deprived of their trainer qualifications.
This rule is like a barrier, barely balancing the gap between families and civilians, and returning the battle to the essence of tactical coordination, energy control, and tacit understanding of partners. But under the rules, the undercurrent never stops - family trainers still control the inheritance of high-quality skills, and it is still difficult for civilian trainers to obtain powerful skills.
And when a fast dragon carrying a "full attribute skill teaching system" landed on this land, a storm that was about to break the monopoly and reshape the trainer pattern was quietly brewing.
