Card Appearances:Swift Gaia the Fierce Knight

In Yami Yugi vs. Gansley, with Kuriboh on the field, Yugi activated Rainbow Blessing and Summons Swift Gaia the Fierce Knight (since it's the only card in his hand, he Summon it without a Tribute). Rainbow Blessing allows Yugi's monster to attack Gansley directly, thus making him unable to activate his Deck Master Ability. Yugi attacks with Gaia and wins.
