Arena is the easiest form of PvP in the game, so it's not really a big accomplishment tbh... Also, in arena, power of every team is reduced to around 10k-30k, so, your title is kinda wrong since power are quite equalized for both teams. Not to mention, your ninjas aren't really "easy to get" for everyone so...

I mean, your intention is good, but your content is misleading at best
