Hello whoever is reading this, I have to print out a couple ruling questions since there has been an increase in Dark World decks seeing play. And of course, there are many weird situations that I have been ruling on. So I just want to place where I could put links up, I would use email but this is more beneficial just incase any of you want to read these threads also. I had problems with Magic Cylinder since some weirdo person in another tourney place said that you can't chain to magic cylinder, but you can.

Magic Cylinder
MAGIC CYLINDER
The effect of "Magic Cylinder" negates the attack of one attacking monster, but that monster is still considered to have attacked and may not attack again or have its Battle Position manually changed.

Monsters that may attack twice during the Battle Phase, such as "Hayabusa Knight", that have their first attack negated by the effect of "Magic Cylinder" may still make a second attack.

If the attack of "Goblin Attack Force" or "Spear Dragon" is negated by the effect of "Magic Cylinder", they will not be changed to Defense Position, since Damage Calculation never occurred.

The Damage caused by this card’s effect is equal to the current ATK of the attacking monster.

If an effect is chained to "Magic Cylinder" that destroys the attacking monster, or removes the attacking monster from the turn player’s side of the field (including switching it to your control, or sending it to the owner’s hand), no damage is dealt by the effect of "Magic Cylinder".

Nice to know, thanks.

thanks ken
