Use Metalworkers ability and then use Voltaic Key

voltaic construct (2: untap target artifact creature) metalworker (tap, reveal 2 artifacts in your hand: add 4 mana to your mana pool)

Need 3 artifacts, then you just tap Metalworker and use Staff of Domination to untap it as much as you like then you can gain infinite life, tap all opponents creatures, untap yours after attacking, and draw infinite cards.

just think how nasty that would be. u got...

get tons of atifacts in your hand and use metalworker to add bunches of mana.

Need at least 2 artifacts in hand but leads to a unlimited mana combo. Use Masticore to clear out their army and attack with an incredibly large Metalworker.

Have both Servitors and the Metalworker out, and the Lamp in the graveyard, then sac a Servitor to bring the Lamp to play. You'll get the Servitor back anyways, right?

well, play anthroplasm, then use the metal worker, reveal a bunch of artifacts to pump him up, then use the diplomatic immunity so he cant be target my spells or abilities. good combo!
