You need to be running the correct version of Forge.

“When you download SpongeForge, the name of the file will provide some important version information. It includes a Forge build number which this version of SpongeForge is compatible with. Other builds, even ones differing by only a few build numbers are not supported.”

You appear to have a duplicate jar for “lucky”

I don’t have a duplicate jar:

LuckyBlock_1-10-2_v7-3-0.jar RadixCore-1.10.2.jar
MCA-1.10.2-5.2.3-universal.jar spongeforge-1.10.2-2281-5.2.0-BETA-2303.jar

but it may well be the wrong version of forge. I’ll check that.
