Teferi, Temporal Archmage

How it plays & wins

This is a blue-based artifact control deck built around Teferi, Temporal Archmage. Its plan is to protect its mana and card advantage with a dense suite of counterspells, including Force of Will, Mana Drain, Force of Negation, Pact of Negation, and Mental Misstep, while accelerating into powerful plays through Mana Vault, Sol Ring, Mox Diamond, Chrome Mox, Gilded Lotus, and Basalt Monolith. Card-draw engines such as Rhystic Study, Mystic Remora, and Sensei's Divining Top help it grind out resources, and Cyclonic Rift and Snap handle the opponent's board.

The list does not make its win condition entirely clear. The detected Basalt Monolith and Rings of Brighthearth combination appears to be its main engine for generating explosive mana or value, but the decklist also includes Hullbreaker Horror, Tezzeret, and Urza, Lord High Artificer as possible threats. Most likely, the deck wins by controlling the game, outlasting opponents, and then closing with a large mana turn or a resolved threat. A card-by-card reading alone can't confirm the exact finisher.
