1) if i remember correctly, edo yugito is abit worse bc not only does it remove buffs and shields, it also decreases attack. H*so has super armor so Han might be better but Edo Yugi is immune to debuffs I believe.

2) Edo Jin treasure will be time limited but it will be released only after all edo jins are released one at a time I think.

3)yes, same, around 200 SS for rares on edo jin treasure.
