Lace

The laces are a rare cycle of five instants that appeared in the Alpha through 4th Edition core sets. Each change a spell or permanent to a particular color. They were originally interrupts.

In color wheel order by color,

• White: Purelace
• Blue: Thoughtlace
• Black: Deathlace
• Red: Chaoslace
• Green: Lifelace

They weren't highly sought after rares by any means and were thought to be novelty cards use primarily to change a card so as not to be able to be blocked by a creature with protection from a particular color. Thoughtlace and Chaoslace were used more often in conjunction with Blue Elemental Blast and Red Elemental Blast. Prismatic Lace from Mirage is an improved version of the entire cycle being able to change a spell or permanent to a color of the caster's choice. Moonlace from the time twisting set Time Spiral turned a spell or permanent colorless. All of the color changes are permanent.
