first the german version has tsunade basically for free if she rotates often, you can save for her for 1 month and each month get like say 30 frags of her, she is yours before the new treasures hit the game, second from what I see I think it costs 50 coupons because its got stack rewards like 5 lvl2 magatamas or 10 mood scrolls etc, it even has advanced thread and tactics scrolls too! as long as the rates are ok I think german is better for high level players who have most rares anyway, also the medium and advanced refines are overpriced. in global medium refine is 7 points I think atleast in one of the lucky board it was. So basically if you aren't prepared the german lucky board can fvck you over pretty bad.

yeah dude I am f2p, well semi f2p only recharged twice and according to oasis I think that is considered f2p because they even care about players who spend 500$ per month, so yeah I can even do you one better and say that I have onoki danzo sage jiraiya 4 pains killer bee iruka paradise shikamaru ALL the commons in the game so far and some other rares that I dont remeber and I have only been playing for 3 months and even skip arena and most events like matsuri.

yeah like event only ninjas like hanzo sailor sakura etc.

yeah this way you can get like 2 super rares, e.g you can get tsunade for just recharge and then tobirama or minato by spending the ingots in the rebate event.
