Should I build Toph Metalbender Aristocrat Heavy?

Hey there, I recently built a Toph, The First Metalbender deck. I feel I'm currently in a mix of landfall, earthbending, and artifact heavy strats and don't know if I should condense into one specific strategy or not. I recently bought a bunch of lands to help fix my mana pool as well but haven't updated the deck list.

My question is, should I include cards like [[Greater Good]], [[Slobad, Goblin Tinkerer]], [[Demand Answers]] to sac earthbent artifacts like [[Solemn Simulacrum]] and [[Ichor Wellspring]] to get their enter/death triggers? Should I add more artifacts like those two to continue getting enter/death triggers more frequently? Thanks in advance for the help!
