"Lostlinker" (ロストリンカー Rosutorinkā) is an attribute in Future Card Buddyfight. It is currently exclusive to Lost World, and cards associated with it. It also contains the "Wayfinder" (ウェイファインダー Uwaeifaindā) sub-archetype, which is given to most of the Spells, Items, and Impacts.
The Wayfinders in both Dragon World start by sending cards to the drop zone, and then when Lost World is brought out have drop effects. The Lost World Wayfinders then call the Lostlinkers, and send cards from the drop, hand, and deck to their souls to activate powerful effects!
