If you have not already heard, there have been some updates to the Gameplay sections of www.yugioh-card.com– there is now an Advanced Rules Information section. You can access it by going to the “Gameplay” link button, and choosing “Advanced Rules Information” from the drop-down menu.
Please do look it over, as it contains information you will need to know. There is also an article explaining it posted at http://www.konami.com/yugioh/articles/?p=3799.
As noted in this article, these rules will change how you play the Yu-Gi-Oh! TRADING CARD GAME. These rules take effect immediately.
Many actions can only be used in the “open” state.
- Normal Summoning (including Tributes)
- setting a card
- perform a special summon that does not start a chain
- changing battle position
- moving between phases/steps
- drawing during your draw phase
- declaring an attack
- ACTIVATION OF AN IGNITION EFFECT
- activation of a spell speed 1 spell card.
After any of these actions occur the game state becomes CLOSED. The Game State may only go back to OPEN when neither player wishes to respond to an action.
One more thing: everyone’s lives will get a little easier if you please stop using the word ‘priority’. It has become largely a meaningless term that wasn’t being used properly anyway.
