The Shades are a card archetype created by CrazedWormHole, being a set of creatures of the Shade species, along with several backup cards.
The Shades are strictly focused on backing eachother up. On their own, each Shade is a decent card at best, useless card at worst. If used correctly together however, the Shades are capable of exceptional offense as well as defense. As a result, most of the backup cards for the Shades are focused on giving the user more Shade creatures to use.
