@Yog Sothoth: Um, well, how did they learn it in the first place? Magic is something you need to learn.

The original leaders were sorcerer outcasts who used their magic for personal gain and profit, they found others who could learn the magic and taught them the magic of Escape Artistry and formed the gang. basically the gang's leaders learned the magic from the previous leaders, so that's how they learn magic.
