Pokemon: Even If It's the System, I'll Kill It

Trainers in the elf literature can all grow. In other words, they may be the key combat power at certain special times. As a gym, isn't it mainly about deleting and selecting trainers? If it is allowed to kill and challenge this elf, first of all, it will cause most trainers to not dare to challenge. After all, the gym trainers themselves are stronger than the trainers who have just debuted. Secondly, if there are some bad gym trainers who specifically want to snipe new trainers and become gym leaders, is this allowed? Then, if the gym trainer is allowed to kill the challenger, does that mean the challenger can also kill the gym trainer elves? Are you sure this institutional alliance can remain intact? If an ordinary trainer dies today and a gym trainer dies tomorrow, how can you maintain the alliance system when the low-end and mid-range combat power is constantly attrition? All depends on peak combat power?
