Oh. I wanna that card! It will fit my pumprincess. The most important thing about dueling is style. If you have no style then you have already lost. No matter your ranking. That's why each duelist has its own card theme.
beating someone in duel links in less than 10 turns? what? how can you even do that??? it's not like duel links has fast paced duels that end in less than 10 turns 99% of the time!
I totally agree, I always use a deck suited for the character or at least using one specified theme like Fiend, Dragon, Zombie, Spellcaster, Fairy, Beast. Usually people who prefer meta rage quits against me final turn.
Also, of course they are good. They are meant to be the easiest, most efficient cards. Meta is easy to make use of, and easy to win with. Thats the point.
