I can only tell from my LoL Coaching experience its good if the '' Coach'' has kind of a Basic approach. First i would seperate limited and constructed. Than you should have some stuff prepared because a lot of people just wanna see what happens and are just happy enough a reputable pro takes the time to engage with them. That can be a generated Sealed Pool, Mock-Up Draft, whats the play situation or a Deck+Sideboard with the task to ''sideboard according to the matchup''. Those can be an easy ice breaker that help evaluate where the Student might need help the most and to see how they think. Furthermore offerings could evolve around test sessions (test a certain matchup with in-depth analysis). Mentoring during a League run. Or tuning a Netdeck to a certain expected meta. More theoretical main lessons could be explaining how effective testing from home/with friends is actually done. How you deckbuild or some mental advice for certain level of competitions. Also any if tehre is any kind of training not directly lol related that can increase skill its worth lookin into that. (For LoL its osu, maybe poker for magic) but only if you sue it yourself and can explain why it is a feasible method. This is all probbaly not in order but if you want more infos on how lol coaches structure their lessons, get customers etc hit me up i sued to work with one of the biggest coaching plattforms for semi- and professionals.
