Forum:Tag Duel question

In a tag duel, do cards in your teammates graveyard count towards the effects of your cards? For example, if you had a Shadow Ghoul on the field and 5 monsters in your graveyard, and your teammate and 4 monsters in the graveyard, would Shadow Ghoul gain 900 ATK or only 500?--64.79.177.254 16:27, 10 September 2008 (UTC)
