Teferi, Temporal Archmage

How it plays & wins

This is a blue artifact control deck built around mana acceleration and counterspells. Sol Ring, Mana Vault, Basalt Monolith, Grim Monolith, the Moxes, Gilded Lotus, and Thran Dynamo ramp it into expensive spells, while Force of Will, Mana Drain, Force of Negation, and Mindbreak Trap protect its plays. Rhystic Study, Mystic Remora, and Lunar Insight supply card advantage, and Teferi, Temporal Archmage anchors the command zone. The list does not show one clear finisher. Hullbreaker Horror and the Tezzeret planeswalkers look like the main threats, but the deck appears to win by out-resourcing the table and then closing with whatever gets through.

The one combo the list clearly contains is Basalt Monolith with Rings of Brighthearth, which can generate unlimited colorless mana. That engine can fund large spells or activated abilities quickly, though the list does not show exactly how the deck converts that mana into a lethal or table-ending finish.
