|Type||Roaming Duelist event|
During the event, once the player logs into Duel Links for the first time since the event started (or if already logged-in, once the player enters a Duel World Area, if they weren't at one already), they will be greeted by a cutscene.
Rex Raptor is seen being defeated by a shadowy figure, revealing himself to be Weevil Underwood. Rex seems astonished for being beaten by Weevil, to which the latter responds that he's different from before, and now calls himself "Evil Underwood". Despite Rex not seeing any difference at all, Weevil restates that with his new, stronger Deck, he will get his revenge on Yugi and Joey.
After Dueling Scheming Weevil 15 times, a new cutscene is played. Weevil and Joey are in the middle of a Duel, with Weevil seemingly having the upper hand. Joey is apparently speechless, which Weevil mocks, but then says that he thought "this card" wouldn't work anymore after he learned Weevil was using a new Deck, and activates "Eradicating Aerosol". As Weevil's Inzektors are destroyed, Joey says that, while he respects Weevil for sticking with his Insects, he still has counters of his own.
In addition to the following, standard Duel Rewards were also available by Dueling Scheming Weevil Level 30 or less.
