Soulrune

Soulrune is an archetype whose concept is done by AvzinElkein. Every Soulrune card is a monster with (This card has no Type and no Attribute). The Main Deck Soulrunes have "This cannot be Summoned/Set." while the Extra Deck Soulrunes are Fusions. All the non-Pendulum Main Deck Soulrunes can be discarded to do something, while the Pendulums have "You cannot Summon/Set, except by Fusion Summon. This effect cannot be negated." as part of their Pendulum Effects. This is currently a WIP, since names haven't been figured out yet.
