I got the idea to use the card in Lightsworns from the 2nd place deck by a player, Jess:

His deck is a mix of Zombies, Lightsworns and Spore. I think any card that has effects activated from graveyard should deserve testing with Lightsworns. Notice the art of Spore, it looks like it is glowing in light...

The deck is mainly modified from the previous Lightsworn deck I posted. Notable additions include One for One and Brain Control as well as Spore. The Threatening Roars are for Infernities. The threat is real. You should find Brain Control to be more consistent with 3 tuners in the deck now. Spore takes the place of the 2 'departed' Necro Gardnas and provide additional synchro abilities to Lightsworns. In this deck, Spore has the possibility of synchro-ing 4-8 stars when summoned onto the field and when there is 2 in the graveyard, it becomes a Plaguespreader Zombies without requiring a card from your hand.
There was once a time where Plaguespreader was unlimited and I think Lightsworn players use 3. Spore acts almost like another 2 Plaguespreaders now. I like this version name too because it looks and sounds like it is made in Singapore!
