I can't understand the massive ban on shiranui. I mean: yes, the needed a stronger ban-list but not in this way. In my modest opinion was better to limite 3 squire and spectral sword, which make an otk combo, than I would have limited to 2 solitaire and sunsaga, to make the deck playable. In alternative the could have also limited 3 squire and solitaire and limited 2 spectral sword and sunsaga.
So sorry we don't all throw our credit card to play blue-eyes.
The nerf they got was probably a bit overkill, but they don't have the best track record with limiting before the overkill. Case in point, Alister wasn't hit until one year, despite being a tutor for one of the best fusion cards, which was essentially free since you can GY fuse, and being able to be a hand trap akin to Gem Merchant.
