the only deck that really works is Sylvians! I tested over five decks, and I'm sure of that. Just switch a level 6 Sylvian for a card that allow you to inflict piercing damage. I a match she summoned three monster in my last turn, and I couldn't inflict damage.
Why would someone tell that a deck works if it does not? Are you stupid? And another thing, stop complaining here, if the deck does not work for you try to figure out how to make it work, add new cards, exchange the cards the site suggested, use your damn brain!
well i build plenty of decks and sylvans are most consistent easily available for this imo; and working doesn't equal winning consistently. thats the gap
I can assure you that although I did not get a 100% win/rate I also didn't get a failure of 90% times as the "Sylvan is the best" guy said. Everyone should use the deck more suitable to their needs but saying that Lab Builder is "b.s" is also not true, it works!
