Hi, I recommend saving them up for future events, or a least save a portion of them up, because for most events, if you wish to save up for a costume, or a powerful time-limited ninja, it will require a ton of coupons to exchange for them. Unless you recharge very often, it will become more difficult to obtain coupons as you level.
If you would like to buff your current team, I suggest you to spend coupons on refining, because magatamas are very easy to save up from ninja exams. Even though some may think refining is very chance dependent/coupon draining, and do not influence your power very much, those should not be the reasons for ignoring it.
The reason for that is, there are very few ways to increase those stats, which play a crucial role in battles, such that winning rate may be dependent on your initiative. Why so? For example if you are facing a controlling team, if their initiatives are higher, they may cause conditions to your entire team that prevent them from moving. With high initiatives, it is possible to defeat opponents that have 10k more power than you.
I'm not saying the main stats (attack, defense, ninjutsu, resistance) are not important, it's just that those additional stats should not be disregarded.
In terms of what type of magatamas to give to each of your ninjas, distribute them with accordance to your ninjas talents.
For example, giving gai sensei whose talents are all taijutsu based attack magatamas would be a better idea than to give him ninjutsu ones,
also giving earth main defense ones, and life magatamas to choza etc.
make sure to give life, defense and resistance to those in the front row for a better survival chance though.
