— Event description
Synchro Festival is an event that took place in Yu-Gi-Oh! Master Duel from April 12, 2022 to April 22, 2022. The second iteration ran from 19 June 2023, 14:00 (EDT) through 28 June 2023, 23:59 (EDT), parallel to the "Legend Anthology: Academy" event.
During this event, the player can earn Medals by Dueling using a Loaner Deck or their own Deck. They earn 500 Medals when they win and 50 Medals when they lose, regardless of whether they're using a Loaner or their own Deck. No Medals are earned if the player surrenders.
This event's missions were combined with the ones for the "Legend Anthology: Academy" event also running at the time, compiled under "Festival (June)". However, this event's introduction added the following missions, which could also be subsequently completed in the "Legend Anthology: Academy" event.
A "Ghoti" Deck that takes advantage of banishing. The Level 2 "Ghoti" Tuner Monster has an effect that Special Summons itself to its own field at a specific timing, if it was banished. Prepare your field during your turn, and use the effects such as that of "Paces, Light of the Ghoti" to Synchro Sumon a Fish-type Synchro Monster on your opponent's turn. If you can Special Summon "Ghoti of the Deep Beyond," you can banish all of the cards on the field!
A Deck featuring ace cards that are DARK Dragon-Type Synchro Monsters, such as "Red Dragon Archfiend." By Synchro Summoning "Red Rising Dragon" with "Crimson Resonator" and a Level 4 monster, it is possible to Synchro Summon "Red Supernova Dragon" that has high ATK and powerful effects. Use Trap Cards sucha s "Red Reign" and attack ferociously.
An "Icejade" Deck, with "Icejade Gymir Aegirine" as its new ace acard. Not only does the effect protect monsters on your field from being destroyed or banished by your opponent, if you activate it on your opponent's effect, you can further banish your opponent's cards. Powerful Synchro Monsters can also e quickly Special Summoned by utilizing Level 7 Tuner Monsters such as "Icejade Creation Aegirocasses," so be proactive in Summoning them.
