i never said any particular deck for the reason that any deck that wins by dealing damage AND uses 6 supernovas can and does benefit from throwing in 1 UG and/or 1 nightmare. and i know this from a lot of deck making and testing over the last 2 months, since i was offline but was able to get the .swf of the trainer from connecting at my sisters. ive made and remade many decks, and have found that a set of decks work particularly well in pvp and ai3, but supernovas in a deck usually mean rainbow, if not youre weird, and UG is only one card which can easily replace quite a few redundant cards in many ccyb variants, and i say redundant, because there is only 1 copy of the card in the deck anyway, and UG is a better choice usually when dealing with ccyb decks, but in general, 6 supernovas in a deck, throw in a UG and test it out for a week, then decide whether or not it is worth using.
i do test things before i post, and i know for a fact most people that respond do not and are assuming what they are saying is right. please test things out before making posts against what i say, you cant argue with no facts, it just doesnt work, and on that note, ONE UG in a deck with SIX SUPERNOVAS is a great idea
