Arcum Dagsson

How it plays & wins

This is a fast artifact shell with a heavy blue disruption package. Moxen, Sol Ring, Mana Vault, Grim Monolith and Ancient Tomb accelerate out the early turns. Arcum Dagsson converts cheap artifact creatures like Memnite into noncreature artifacts, such as Isochron Scepter. Free counterspells, including Force of Will, Force of Negation, Fierce Guardianship, Misdirection and Mental Misstep, protect the plan, while Rhystic Study and Mystic Remora generate value along the way.

The clearest win is Isochron Scepter imprinted with Dramatic Reversal. With enough mana rocks that tap for at least three mana in total, each activation untaps everything and nets mana, which gives infinite colorless mana. Walking Ballista is the natural outlet, turning that mana into counters and pinging the table out. Beyond that, the list has no other combo I can confirm, so the deck leans on this line and on Ballista.
