A Duel with Dartz (6) - S1.E182

Dartz calls forth Divine Serpent Geh, a sinister snake with infinite attack points! Yugi counters by joining the three legendary dragon knights into the mighty Timaeus the Knight of Destiny, but is that enough to combat a monster with limitless strength? As the great forces clash, the gateway opens for the final endgame as the world-devourer Grand Dragon Leviathan and the legendary Atlantis rise out of its watery grave!
