, Tap X untapped artifacts you control: Look at the top X cards of your library. Put one of those cards into your hand and the rest into your graveyard.
Partner (You can have two commanders if both have partner.)
Glacian turns a wide board of artifacts—especially Powerstone tokens and mana rocks—into a repeatable card-selection engine, tapping X artifacts to dig X deep and stock your graveyard. You ramp out artifacts and Powerstones early, then dump cards into the yard to enable reanimation/recursion or simply out-value the table while assembling an artifact-based combo or big payoff. With Partner, you pair Glacian with a second commander to add a color or a more aggressive plan.
Add fast mana and Powerstone generators (Mana Crypt, Sol Ring, Karn, the Great Creator, The Mightstone and Weakstone) to come online faster, and pick an efficient Partner—Tymna for cards, Kraum or a black partner for recursion/reanimation. Tighten the deck around an untap engine (Unwinding Clock, Voltaic Construct, Clock of Omens) for explosive turns, and include a clean win like Thassa's Oracle to capitalize on the self-mill. Finally, run strong artifact protection and counterspells to defend the engine from sweepers.
