Rush Duel

Rush Duel is a format for Yu-Gi-Oh! Official Card Game. It is featured in Yu-Gi-Oh! SEVENS anime.

Rules
When the turn starts, the turn player draws cards from their Main Deck, until they have five in their hand. Both players can Special Summon as many monsters as possible during a single turn, called Continuous Summon, though they can Normal Summon only once per turn. However, the players can only use cards designed for Rush Duels, which have a special frame and a tag "RUSH DUEL" at the bottom of the card.
