With Maliss making its debut some time ago, it was only a matter of time until Ryzeal would be coming into the picture.
New Selection Packs
Two selection packs have just been released: Tales of the Witch and Detonate to the Top Speed. The former focuses on Diableeze the Original Sinkeeper, and surprisingly, a lot of the Relinquish support and retrains came along for the ride.
As for the latter, while the Ryzeal archetype is the main draw, it's accompanied by the new Six Samurai support alongside the last of the Mulcharmy trio of hand traps, Mulcharmy Meowls.
Tales of the Witch

Diabellze the Original Sinkeeper has very strong synergy with the Chimera (Phantom Beast) archetype because of its status as an Illusion monster.
With how the Phantom Beasts can easily extend into other Illussion-type monsters with Nightmare Apprentice or recur bodies through Chimera the King of Phantom Beasts, Diableeze the Original Sinkeeper can easily find a home in a rather robust rogue deck.
As for the Relinquish and Restrict retrain/support, they’re not anything new to Master Duel.
As far as gimmick decks go, they can be rather irritating to play against if they’re able to establish a board. Funnily enough, Millennium-Eyes Restrict counts as a ‘Millennium’ monster when using the effect of Millennium Ankh for decks making use of The Unstoppable Exodia Incarnate.
Detonate to the Top Speed

Ever since the Maliss archetype was introduced to Master Duel, players have been wondering how long it would take for Konami to introduce Ryzeal to the digital format.
Now, one of the strongest archetypes in the current competitive scene of the physical Trading Card Game (TCG) has been ported over. Unlike the TCG, Ryzeal Detonator will be at full capacity in Yu-Gi-Oh! Master Duel. Unfortunately, the same cannot be said for the archetype itself.
Ext Ryzeal is currently at a semi-limited state, and the Mitsurugi archetype that is often partnered with Ryzeal has yet to make its debut.
That’s some small comfort, though, as even without all of its contemporary tools, Ryzeal is still a force to be reckoned with. With the Fiendsmith cards and the whole gamut of the Mulcharmy trio available, Ryzeal will more than likely follow the same story it carved in the physical format.
As for this selection pack’s other featured cards, the Six Samurai retrains and support have been finally ported.
The writing was a little on the wall on this, though. A few weeks ago, there was a minor change to the Master Duel Forbidden/Limited list, and Gateway of the Six, one of the archetype’s strongest combo enablers, was recently brought back to unlimited status.
Gateway of the Six allowed the Six Samurai archetype to do some pretty degenerate boards. This particular Spell card could essentially act as a lingering RotA (Reinforcement of the Army) for the archetype.
Normally, this isn’t too bad in of itself. Having a RotA effect is basically standard for modern decks now, but more than one Gateway of the Six on the field, coupled with the fact that the Six Samurais can easily special summon bodies onto the board, can let this spell card generate an extra 1-3 card advantage off just two bodies.
With the new Legendary Lord Six Samurai - Shi En able to negate monster effects, original fans of this archetype may find new firepower to compete with modern rivals.
Free Legacy Pack Tickets

Rounding off this little announcement, Konami is currently running a survey for Master Duel. After completing the survey, a player can redeem 10 Legacy Pack tickets. Legacy Packs aren’t anything too outstanding in their own right, but a player could get lucky.
You can find the survey in the Notification section of the game. Just navigate to the notification that reads, ‘Survey Regarding Gameplay’, and then click the ‘Survey’ button located at the bottom right of the menu.
Once you’ve finished answering the survey, the Legacy Pack tickets are automatically redeemed and can be used in the Bonus Pack section of the shop.
Interested players will have until the 13th of August to complete the survey and gain the 10 Legacy Pack tickets.
