This core is broken. Mamo is a great lead against basically everything other than custap skarm/forry, and they're both so predictable you can lead with Mag and force the opponent into only getting 1 layer. Essentially it forces the opponent to killing Mamo with a bulky water, which Cube can sub on with impunity. So feel free to let that rotom-w hydro pump away on your mamo, with full knowledge that you're going to get a sub up with the most broken poke in OU.

As for set explanation, Icicle Spear is used on Mamo over Endeavor/Crash because it allows you to beat opposing sash leads (namely Breloom and Smeargle) and the newer mixnite lead before they can do anything. Jolly nature is used to outspeed jolly breloom and +speed smeargle. Cube's last move slot is split between Earth Power and HP Fire depending on what your team needs removed. HP Fire is great for those scizor switch ins who think they're going to break your sub with u-turn only to be ohko'd, but Earth Power definitely has merit as a way to deal with Heatran and Jirachi. EVs provide 101 hp substitutes, allow you to outspeed jolly mamo, and the rest is dumped into attack. Magnezone's specs set is the best it can provide in the meta IMO, and it allows you to clean up the bulky water Cube originally set-up on. Timid is used to outspeed most scizor variants.
From this core you can move towards drag mag pretty easily, but there's also potential to build around other threats that like having steels removed. I've had success with this core + scarf + bulky set-up sweeper + breaker.
Hopefully enough people abuse this core that Cube is suspected again. It really has no place in OU.
