Breaker is currently worded to effect the difficulty of the next card played. A card is not "played" until after the CC has passed. Changing difficulty at this point won't do much.
Obviously we all know HOW breaker is supposed to work (well, with blocks it may not be clear to all, but as far as a form) and I am not trying to nitpick or point out errors or mistakes. Maybe this has already been noted, but otherwise just a heads up to maybe change the next rev of AGR to say "the next card attempted to be played" or (this would change game mechanics, not sure how hata, steve, etc feel) maybe even change it to increase the difficulty of the next CC made. (not saying i recomend that, but it may be an option)
Again, not trying to do the "card text says this, so im gonna play it this way" thing and be difficult, just a heads up.
Also if there is somewhere else these "requests" should be posted feel free to let me know, i didnt think it was right to post in the sticky errata topic.
