I was play-testing a Lightsworn deck at home (who's mechanics I discovered entirely on accident) when I realized to myself "Damn, this could be really good if used right!", so I made a more playable and fun version of this deck in this website!
Basically, the Lightsworn monsters kill themselves in order to give power to other Lightsworn monsters, specifically cards such as "Gragonith, the Lightsworn Dragon", and "Judgement Dragon". It's an archetype that's tricky to play, due to the fear of running out of cards in your deck (because trust me, it will happen fast if you're not careful), but if you manage to master this deck and use it to its ful potential, it can be a scary deck to fight against.
One more thing to note about this deck is that although it can die fast, it also becomes seriously strong really fast as well.
If you have anything you would like to say or recommend about this deck, please feel free to do so. :)
