... I JUST bought 3 Copies of Cyber Valley for my D.D. Immortals (I saw one guy try it on TCG Player, but IMO, his deck is far less explosive than my build, its a tricky hybrid)... The reprint of Dimensional Prison is cool, I suppose soon, I'll have to be more careful playing Stardust at Locals.
Card Trader is decent, so I suppose its a good addition. Is it just me, or does Konami really know how to make packs. Special Editions with such good cards, not to mention reprinting everything for us. *Crosses fingers for JD reprint*
I feel its good to bridge the gap between the casual player and tournament players... speaking of tournaments, Trag in French Twilight isn't a bad choice. Its not like Lightsworn need to play too many cards from their hand, so Trag can be a fair beatstick, not to mention the speed with which cards can hit the grave is a lot, allowing for Trag's other effect to allow for a desirable synchro with Plaguespreader. IMO, its better than Gorz in Lightsworn. It stops OTKs just the same, can be dropped easier than Gorz and also if you need a free reset, mid game, JD fills that role perfectly.
I wouldn't call Twilight Lightsworn with Chaos Sorcerer, the dark count increases beyond that of a few Necro Gardna and Allure/DAD becomes viable. Twilight does play similarly to Lightsworn, except you trade some of the effects of Lightsworn mills for those you can get from the DARKs you splash in. IMO, when one opts for Twilight, you trade the consistency (face it, Lightsworn mills are better than Twilight mills, though Lightsworn is by no means consistent), for more explosive and greater diversity. The speed you lose can be regained with Allures, so its about the same speed.
Does anyone expect more Duel Terminal Cards to come out? I'd personally like to have Dragunities in the game ASAP and having some AOJ cards released in the next 6 months would make sense with the release of the new Machine Structure Deck.
