You really think its fun to just press "yes" over and over? Then play the AI and don't waste peoples time with your copy/paste deck. If you actually come up with a cool deck of your own then show it off and test it but its not like you're super creative for looking up the best deck.
They get really easy to jam up right now. Most were wankers stuck in lower ranks. So you use counters to block shroom and leaf. Use chaos hunter to block rose lover. The more strategic thinking you force them to do the quicker they burn out. Its rare in my experience to finish off Sylvan. Most just take twelve years to make a move then surrender before the finishing blow.
Also Sylvans big cause for the move to 5,000 life points in june. Konami power crept a weak deck in TCG,OCG in duel links. Its like a fat man bursting his belt from gorging. To big to fit the frame of the game.
Personally, I use it because all my other decks are tear 3 or below and I gathered the minimal ammount of necessary cards in a week. On the other hand, I've been trying to do the same with the Masked hero deck for a month now because I prefer it and I am still half-way there. I would love to play this instead of Sylvans but I can't because I lack 2-3 cards. Sylvans helped me get most of the gems.
