Before reading the rest of this post, read this blog post: http://duelistcodex.wordpress.com/2013/01/08/rules-bulletin-4th-january-2013/
What you need to remember from these updated/new rulings is the following:
- The effect of Light and Darkness Dragon that negates a monster effect resolves at the same time as the attack/defense decrease.
- A banished monster that was special summoned is still treated as special summoned after it returns to the field, even if the return itself is NOT a special summon. (card effect like Interdimensional Matter Transporter & Galaxy-Eyes Photon Dragon).
- You can apply the effect of multiple Flashing Carat Dragon, Stardust at the same time, but at that point the destruction negation is only applied once. Better is to use the effect one destruction at a time. Each Carat Stardust can only negate one destruction of one monster, whether it's by battle or card effect. Also, the effect only applies while the target is face-up. you can still use Book of Moon to negate Carat's negation (lol).
That's it for now. Doesn't always have to be a 3-page post, eh.
