I'm skeptical that it can maintain such a high demand going forward, but since Fabled introduced Iconic rarity, it has certainly introduced the perfect height of card chasing for what is a TCG somewhat still in its infancy
In the previous example, we can see that Perimeter Enforcer has a 100% chance of being in the Detectives packet
You can find copies of Yoshimaru for about $6 at the cheapest, but $8-$9 is a more reasonable cost for most Yoshimaru variants
Maleficent, Mistress of All Evil The one and only Maleficent, the sorceress from Disneys Sleeping Beauty, is as iconic as she is for a reason
This card also has a Shift cost of four alongside one ability called You Can Fly!, which gives all your characters Evasive, meaning they cannot be challenged unless the challenging character also has Evasive
This is brand-new and will likely be a type that receives some synergy pieces in the full set, much like Ixalans Caves
