I've experience being lucky on some events but not in Wheel Events .. From Mission Boxes and Lucky Ninja Packs that you get from Lucky Board, i got Hashirama Senju [First Hokage] 3 times, same with Tenten [Great Ninja War] 3 times also .. Aside from that, already got Treasured Tools Ultimate Essence so many times from Free Draws in Ability Treasure but only once from the Mine Plunder ..

Wheel Events are not my friend at all ..

I forgot to include, got Hiruzen Sarutobi [Third Hokage] once .. But after that drops, haven't got anything till now ..
