Chain of Smog

Chain of Smog was released in 2002 as part of the Onslaught expansion for Magic: The Gathering. As a rare sorcery, it was designed during a period when the game was heavily focused on tribal synergies and the return of the cycling mechanic. The card features a unique effect that allows players to copy the spell repeatedly, a design choice meant to encourage chaotic, high-interaction gameplay moments characteristic of the block's experimental era.

The card's atmospheric illustration was created by artist Heather Hudson, who was a frequent contributor to the game during the early 2000s. Her design for the piece emphasizes the suffocating, dark fantasy aesthetic central to the Smog theme. While it was initially viewed as a niche card due to its symmetrical drawbacks, it has since become a significant piece of combo-centric deck building in formats like Commander, where its ability to create an infinite loop with specific cards cemented its lasting presence in the game's history.
