Hey !
i just pass'd it (french server) with 140k, NO DIFFICULTY LOWERED

Gaara - Minato jonin -x
x - Earth - x
x - Konan - x
4-3-2-2-2 ; Maneki neko and Pakkun on mystery
You need tons of luck with edo hiruzen and edo tobirama, but it's possible with many retry
You need to bring Gaara barrier for the second fight
After each Kage attack, use earth main mystery first to proc dodge and Tag, then Focus hiruzen edo with Jonin and Gaara and focus Edo minato with Konan

Good luck !
