There was a press release today on Konami's site mentioning a few releases scheduled for the laster part of this year. The only one that I think hasn't ever been mentioned before is the Realm of Light Structure Deck, presumably a reprint of the Japanese Lightsworn Duelist Set, which will be released on June 27th. Prepare for your locals to get extra sacky, just in time for the summer!
Konami throws a curveball! Apparently, the TCG version of the deck will come with a brand-new World Premiere Spell Card called Lightsworn Sanctuary, which will, according to them, address a longstanding weakness of the archetype. So as I said before, prepare yourselves for a sacktastic summer!
03/19/14 Update: ARG apparently found an image of the Structure. Cool!
03/20/14 Update: Found closer image of the Structure. I have to admit, as much as I hate playing against it / how degenerate it is, I'm excited for this deck to come out. The deck is relatively fun to use, and at the very least, maybe Judgment Dragon will get Limited.
