Card Appearances:Infinite Cards

In Yami Yugi vs. Strings, Strings used this card to increase Slifer the Sky Dragon's ATK to incredibly high levels (Slifer's ATK and DEF is equal to 1000X the number cards in the controller's hand). He used four other cards to constantly increase its ATK while protecting his own Life Points.

Jam Defender redirected all opponent attacks to Revival Jam, which would immediately Special Summon itself back to the field. This activated Card of Safe Return, allowing him to draw three cards and due to Infinite Cards, there is no limit to the number of cards in both players' hands.

This four card combo made Slifer almost invincible. However, it had one fatal flaw and Yugi and Seto managed to figure it out. After attacking Revival Jam with Buster Blader, Yugi activated Brain Control to take control of Revival Jam as it regenerated itself. When it Special Summoned on Yugi's side of the field, Slifer was forced to attack it and Revival Jam Special Summoned itself to Yugi's side of the field, forcing Strings to draw three cards, then Slifer attacked again. This loop went on and on until Strings's deck was empty and thus, he loses the Duel.
