1. Lifepoints

All four duelists start with 8000 LPs. If a player loses all of his/her LP's, that team loses.

2. Decks

Everything here is the same as a normal duel, using 40+ cards etc.

3. Turns

Let's pretend we've got two teams dueling, Team 1, and Team 2. The first member of Team 1 goes first. Then the first member of Team 2 goes next. After that, the second member of Team 1 goes first, and then the second member of Team 2. Hope you got all that. Let's spell it out in English for you:

TEAM 1 MEMBER 1 > TEAM 2 MEMBER 1 >

TEAM 1 MEMBER 2 > TEAM 2 MEMBER 2 > Repeat

4. Effect Cards

If you play a card that affects all monsters, it only affects the Duelist you choose. Raigeki will destroy all monsters on whichever of you're opponent's field you choose. Harpies Feather Duster destroys all of the chosen opponent's Magic/Trap cards. For things like dark hole, you destroy all of your own monsters, and a selected opponent's monsters. Get it?

When using cards that activate due to an opponent's move, it only affects the attacking opponent. This happens with cards such as Mirror Force.

5. Protecting

Yeah! You CAN protect your partner! But there's a stipulation here. Firstly, you can only protect your partner if he is being attacked directly. Secondly, when protecting your partner, the card you use must be FACE UP. It doesn't matter what mode it is in though. From there, everything else works as normal!
