Elena had two very simple plans. Firstly she was going to collect many metals and minerals with various special effects. Then using her own Devouring and Assimilation ability, she was going to perfect those metals and create an even better version of them.
The next step of this first plan would then depend completely on Golden Elena. With her help, Elena was going to create as many swords as possible and store them in her inventory.
So next time, when Elena would use any move, like the convergence of swords, that needed multiple swords to work, she would be able to release an insane amount of power because of how high the grade and the quality of the swords made by golden Elena were.
With the success of this plan of hers, Elena would immediately gain an amazing and super trump card. Something that she could use without hurting herself or it having some kind of limited use and cooldowns.
