() The last ability will trigger, at most, once per combat damage step. That means (1) the ability won't trigger at all unless you control an artifact as your upkeep begins, and (2) the ability will do nothing if you don't control an artifact as it resolves. You can revive two of your best artifact creatures right away to keep up the pressure, like Wurmcoil Engine, Sphinx of the Steel Winds, or Blightsteel Colossus. Thopter Spy Network's first ability has an intervening ‘if' clause. A boardwipe won't feel so bad if you cast Sharuum with Panharmonicon on the field. You can also make use of sacrifice outlets, or trade creatures in combat if you can use Sharuum's ability many times. Synergy cards are strong here too, such as Strionic Resonator and Panharmonicon to double any triggered ability you are using, such as Sharuum's own. There are some cards out there you don't want to see on the battlefield at all. Whenever one or more artifact creatures you control deal combat damage to a player, draw a card.

Counterspells are also a good call, from Dissolve to Render Silent and Pact of Negation. Similarly, use spot removal for any permanent type, from Swords to Plowshares and Utter End to Mortify and Detention Sphere. Two to five board wipes will likely do for a deck like this, and Scourglass should definitely be among them. Whenever one or more artifact creatures you control deal combat damage to a player, draw a card. If the board state is hostile and you don't have a combo, use the many boardwipes in these colors: Wrath of God, Damnation, Scourglass, Merciless Eviction, Cyclonic Rift, or Supreme Verdict. Card Type: Enchantment Casting Cost: 2UU Card Text: At the beginning of your upkeep, if you control an artifact, put a 1/1 colorless Thopter artifact creature token with flying onto the battlefield.
