Unfortunately, the rerun doesn't give out a large amount gems again but this is just a showcase showing that legends since last year don't have a hard time clearing this island in 2018.
Replacements: Law+ with Sengoku Qck but I highly recommend Law for his pinch healing. Ray v2 with any block orb remover/ orb booster (raid Kuma etc.) GPU with maybe Maggy + but I think GPU is better so you get the higher hp boost.
