Lita, Mechanical Engineer can untap these artifact creatures to act as blockers on your opponents turn

If you're already in the Undercity dungeon, then cards that read venture into the dungeon will instead progress you to the next room in the Undercity as opposed to having you enter another dungeon

Classic artifact lands like Seat of the Synod or Great Furnace are also excellent because they come in untapped and fuel all your artifact synergies without costing you deck space
