Ante Duel
An Ante Duel is a Duel where both players stake cards of equal value, and the winner of the duel claims both cards. This is the only way to become the Owner of a card in a duel. These Duels are completely optional but are forbidden in most official tournaments.
In the anime and manga, these Duels were more common. In the manga, ante is said to be a common rule in trading card games, and ante duels were required in the Battle City tournament. In Yu-Gi-Oh! GX, however Duel Academy's policy forbids Ante Duels between students. In season one of GX, there were a few cases of Ante Duels. Despite posing as a Shadow Duelist, Titan would also take all rare cards away from his opponents. Brier and Beauregard, challenged Obelisk Blue students in unauthorized Ante Duels before Dr. Crowler "hires" Jaden to defeat them. Later is introduced Trapper, a man who takes most valuable cards from his opponents, and later sells them for a great amount of money. There aren't any Ante Duels in Yu-Gi-Oh! 5D's.The only Ante Duel in Yu-Gi-Oh! ZEXAL is where Yuma tries to get Bronk's deck back from Shark.
Players that play with an ante usually bet a rare card that isn't a part of their Deck, as many players tend to be afraid of losing cards from a Deck they spent time building and balancing.
