Millenium Tauk- This item is owned by Ishtal Isis. The Millenium Tauk allows you to see into the future, but another Millenium Item may change that future.

It holds the ability to predict into the near future. In manga 27, Isis gives the Tauk to Yugi, and therefore Yugi is the new owner...no other info. ^_^ but the Yugioh series hasn't ended yet. Maybe more information?
