This card can only be used by a "Bearer of the Core's Light".
Main - Look through your whole deck. You can summon a "Wurm"-named Spirit from it, without paying the cost. Then, shuffle your deck.
Flash - During this turn, a Spirit you control gains +1000 BP. By sending three cores from a "Galaxian"-family Grandwalker Nexus to the Void, instead, refresh a "Wurm" named Spirit you control.
