Trying to do 36 challanges (need all rounder) budget is like 400 div

I will be honest I have been struggling for 2 days now to figure out what to play. I really need some advice.. The top 3 builds imo to complete the challanges are LS (fub version), zenith and mfa... but all those 3 seem so expensive that even 400 divs doesn't seem to be enough for what they require. Any advice on what a good all rounder is or a different ls (that doesnt need atleast 1k divs like fubs) would be appreciated. MFA is the cheapest from the 3 but I just dont like the mechanics
