Most of you should be aware of the changes, however i understand some of you are not. Since 10th July some cards with the text "until the end phase" was changed to "until the end of the turn" meaning that some cards went from powerful to super powerful.
One of the most important cards to be affected by this was the revision to Effect Veiler. This means that it is now able to negate the effects of cards such as Yameto and the milling effects of Lightswarn monsters.
A full list of cards that was affected by this change can be found here: http://shriek.twoday.net/stories/909745299/
