Gotta go fast.
The main concept about Yu-Gi-Oh! Sevens is focusing around Rush Duels. But what are Rush Duels, exactly?
From the brief Q&A held at the JUMP Festa with the main cast, “Rush Duel” is a new concept created by the protagonist, Yuuga. Apparently he doesn’t like the concept of “rules”, but rather building his own road forward (of course “road” being a pun on his own name).
However, we quickly learned that from April 2020, Rush Duel will also be introduced as a new product for the OCG, as in, the physical card game.
As explained in this schedule, on the right side of the “April 2020” red bar in the middle, the product branches into the existing 11th product season of the Official Card Game (with Rise of the Duelist being the first product of the season) and Yu-Gi-Oh! Rush Duel (with an unnamed product). This also matches the premiere of the Yu-Gi-Oh! Sevens anime, as well as the application of the Master Rules April 1st 2020 Revision.
The three characteristics of “Rush Duels”:
1) Uses specialized cards. New cards that are easy to interpretate and very attractive are introduced!
2) Continuous Summoning. You can Summon any number of monsters per turn!
3) Mass drawing. Each turn, you draw until your hand becomes 5!
For the second point, the stream clarified that for example, under the existing rules, you are only allowed 1 Normal Summon or Set per turn. In a Rush Duel, as long as you have monsters in your hand, you can keep playing as many as you want. If you have a Level 5 or higher monster, you can Tribute Summon it as usual in the same turn.
The third point replenishes your hand after playing several monsters from your hand, by drawing cards in each of your turns until your hand size becomes 5.
