Leyline of Singularity card art
Leyline of Singularity makes every nonland permanent a Legendary permanent — a global rule change that warps entire boardstates the moment it hits play, or before the game even starts if it's in your opening hand. The cost is real: it shuts down token strategies and creature-copy effects for you just as much as for opponents, so running it with Ioreth of the Healing House or any token-reliant win condition is a hard no.

In Commander, Leyline of Singularity is a niche hate piece that earns its slot specifically to punish token-based strategies and mass-copy combo lines — it turns every Goblin token, Treasure token, and cloned creature into a legend that dies immediately to the legend rule. Legacy and Vintage have faster, more redundant ways to close games, so the Leyline sees essentially no competitive play there despite being legal. Modern's hate-piece ecosystem is crowded and more efficient options exist for most threat categories, leaving Leyline of Singularity on the fringe. It's effectively a Commander card.

Price Context

Current price

$4.50 cheap tier

At $4.50, Leyline of Singularity sits comfortably in the budget tier — cheap enough to pick up on impulse for any blue deck with a legitimate use for it. It's a niche card with a stable, low ceiling on demand, so don't expect the price to move meaningfully in either direction.
