The duel against Dartz (DLC or in Link Evolution), due to Yugi's deck being a textbook example of Awesome, but Impractical: more than half of his monsters require tribute or, in the case of the legendary knights have strict special summoning conditions, thereby putting you at enormous risk of bricking, and the few that can be summoned right away have such paltry attack that you'll most likely just set them.Unless Yugi bricks hard, you're not gonna finish this one.

Yugi's deck in that duel is an Underdog Exodia deck that adds in a good number of banned cards, field-nukes, and stall, while Kaiba's lacks anything special beyond Ancient Rules and a nerfed Crush Card. For much the same reason as the above two, playing as Kaiba against Yugi in their first Duel is pretty much impossible.But really, it just makes sense Weevil is a Warm-Up Boss when played as Yugi, what makes you think you'd have better luck than the AI? Weevil's deck has absolutely no answers to either monster, and Ra help you if Yugi Fusion Summons Gaia the Dragon Champion (2600 ATK). While Cocoon of evolution can get a boost from the Forest Field Spell to achieve 2200 DEF, increasing its survivability, Yugi will almost always have enough time to draw and summon his Dark Magician (2500 ATK) or Gaia the Fierce Knight (2300 ATK). In order to summon them, you have to be extraordinarily lucky enough to draw four cards: Petit Moth, the Cocoon of Evolution to equip to it, either the Great Moth or Perfectly Ultimate Great Moth to be summoned by Tributing a Petit Moth with a Cocoon of Evolution equipped after 4-6 turns, and the Swords of Revealing Light to buy you time, without which your Petit Moth is unlikely to ever last that many turns. Weevil's only high-ATK monsters are the two monsters considered to have the worst summoning conditions in the entire game: Great Moth and Perfectly Ultimate Great Moth. Yugi, on the other hand, has his standard deck, which has three high-ATK monsters that can be Tribute Summoned. Weevil has virtually no high-ATK monsters in his deck. The first Yugi/Weevil duel becomes this if you play as Weevil using his deck.He'll brick eventually, but he's likely going to beat you at least once before that happens. And on top of that, Yugi's deck is pretty poor offensively, meaning Seeker will usually survive long enough to get a few more draws in. Dueling him is entirely a Luck-Based Mission if he gets even slightly lucky on his opening hand, he will win on his first turn. Seeker is something of a case of this he runs three copies of every Exodia part and multiple banned draw cards.Even if you do manage to summon Flare Neos under ideal circumstances, it doesn't have enough power to OTK Alexis, and it will have to because of its Hour of Power. Alexis, on the other hand, runs an Ice Counter deck that's extremely capable of shutting down your meager offensive options. What you do get is a ton of bricky or useless cards, including Spark Blaster, Air Hummingbird, and Ojama Black.

The Jaden/Alexis duel (where Alexis has an Ice deck) is similarly hard, for more or less the same reason: because Jaden finished the duel with Flare Neos and didn't use Neo Space in that Duel, Flare Neos is your only Fusion and you don't get Neo Space.Jaden's Elemental Heroes are played pure, more consistent, and flat-out better than your cards. On top of that, the Destiny Heroes Aster runs in that deck are some of the worst ones available, and the deck as a whole has almost no offensive potential unless you get insanely lucky. Problem is, Aster had the Magic Poker Equation, and you don't you have to run the same Elemental Hero/Destiny Hero combo he did, a combo that has absolutely no synergy whatsoever.
