Sharuum Artifact Combos (EDH / Commander)

Lots of combos, probably not enough control + card draw to find the pieces, but whatever

Some Combos:

Infinite Mana (add gemstone array to the colorless ones for colored mana) -
Training grounds + Filigree Sages + Mana rock that taps for at least three
Thopter Foundry + Sword of the Meek + Ashnod's Altar (also gets infinite life and tokens)

Graveyard Loops (add marionette master/disciple of the vault to win)-

Version 3 - Gets infinite colorless and infinite Sharuum ETBs (This one's complicated and I don't know all about the stack, so it might not work)
Pieces: Mirrorworks + Sharuum, the Hegemon + Ashnod's Altar + WBU5 open

1. Cast Sharuum, paying for mirrorworks
2. With Sharuum's ETB and the mirrorworks ability on the stack (so that mirrorworks resolves first), sac sharuum and let her go the graveyard for two colorless

6. Let the copy's ETB resolve, bringing Sharuum back; pay for mirrorworks with two of the floating colorless
7. Repeat 2-6 as needed

Version 4 - Makes infinite colorless
Pieces: Junk Diver + Myr Retriever + Ashnod's Altar + A cost reducer

1. Sac both to Altar, returning one with the death trigger
2. Cast that with either 1 or 2 of the floating mana (because they are discounted)
3. Sac it to return the other
4. Rinse and repeat

Version 5 - No real payoff
Sharuum, the Hegemon + Sculpting Steel

1. Have Sharuum in play and cast Sculpting Steel, copying Sharuum
2. State-based actions happen, and one of the sharuums go to the graveyard
