This is getting its own topic because I think it's actually VERY important.
http://www.ygorganization.com/ocg-321-ocg-ruling-reviews/The main thing that concerns me is the field spell ruling being changed from what it was. Now Geartown, Meklord Fortress, Karakuri Shogun Castle, Chaos Zone, and other field cards that do things upon being destroyed won't activate if you set a new field card like they did before. That and the double field spell thing basically means that no one's going to use these cards anymore
Also the damage calculation thing is sorta confusing... if I'm understanding this right, now Honest has to be activated before cards like Forbidden Lance and Shrink but after cards like Mirror Force and Utopia?
Here's something else - maybe a more relevant example for TCG would be, if you use Forbidden Lance on a monster that has been summoned with Rekindling, now it's still banished at the End Phase. I mean that is more fair, but it does contradict the way we've viewed the card before.
And best for last, they actually made a ruling about Cocoon of Evolution. Oh that pesky card has been popping up in the meta so much lately, hasn't it?
