I read your article today about how it wasn't confirmed what Japanese sets would be included in the American Magic Ruler. However, after looking at one of the Promotional Flyers
[http://www.tpdigital.net/users/bnsebay/PreSells/0721yugiohmagicruler3.jpg]
I noticed something that could be confirmation. On the flyer, there are pictures of three cards - Relinquished, Toon Summoned Skull, and Toon World. The first 'Toon' cards were released in the Japanese series Pharaoh's Servant. Relinquished is in the previous set, Magic Ruler. Since all three of the cards on the flyer are translated, it is most likely that both Magic Ruler and Pharaoh's Servant will be included in the English Magic Ruler. Combined, the set would have a total of 101 cards [50 from Magic Ruler, 51 from Pharaoh's Servant.] Hope this helps, keep up the good work!
