Card Rulings

July 25, 2025
An “artifact source” is any object with the card type artifact. This means you could spend the mana from Steelswarm Operator’s last ability to activate an ability of an artifact you control or an artifact card in your hand or graveyard, for example.

Price History

Wizard conjuring a magic the gathering cards

To study a single card is to glimpse the heart of a spell - a frozen moment of ambition, artistry, and arcane intent. Within each glyph lies a spark: a story untold, a duel turned, a destiny altered. Treat it not as mere parchment, dear seeker, but as a shard of the Multiverse itself.
