In the game Yu-Gi-Oh Duel Links, players earn Gate Keys which allow them to duel against Legendary Duelists from the original series, GX, 5Ds and the movie Dark Side Of Dimensions. With such a massive choice of duelists to grind against, it is worthwhile to know which opponents are actually worth your time and which aren't.
For that end, we have a list here of the five best duelists to grind against to get the best cards and 5 which have drop pools so pathetic that you wouldn't waste a single key on them. It's time to duel and get your game on!
10 Farm: Seto Kaiba (DM)
In control of the mighty Blue-Eyes White Dragon, the Duel Monsters variant of Seto Kaiba can be an intimidating opponent for newer players but he is also one of the best opponents to farm for a couple of great cards.
The first of course is the aforementioned Blue-Eyes which is a staple of that archetype's deck is generally a great card for beginners and is essential for those wanting to make a deck around it. More importantly, though might be getting Enemy Controller from Kaiba as it's one of the most splash-able (can be put in a lot of decks) cards in the game and is always a useful quick-play spell.
9 Avoid: Joey Wheeler (DM)
Kaiba will surely get a kick out of seeing Joey in the skip section, but it's true: Joey's card drops in Duel Links are quite sad.
Anyone who's watched the anime will know that many of Joey's strategies only work because of his ridiculous luck with draws, coin tosses and dice rolls. In the actual game, cards like Graceful/Skull Dice, and Time Wizard just aren't worth the risk. Combine that with a lack of strong monsters or spells, and we have a duelist to skip.
8 Farm: Alexis Rhodes (GX)
Cyber Angels are a strong deck in Duel Links due to their consistency and powerful effects. In order to get the most of the deck, you're going to want to grind against Obelisk Blue's Alexis Rhodes.
Featuring the staple ritual spell cards of the deck and the powerful Cyber Angel Dakini, this is a character that can be skipped if you don't care about Cyber Angels but if you want one of the better decks in the game, definitely check her out.
7 Avoid: Weevil Underwood (DM)
What can even be said about Weevil Underwood's drop cards? Great Moth? Giant Flea? LEGHUL?!
Obviously, Weevil has without a doubt one of the worst card pools in the game with nothing of value in the entire lot. It shows that in a recent event, they paired Weevil with the much better Inzektor deck rather than these bum bugs.
6 Farm: Yugi Muto (DM)
Not only did Yugi beat Atem in the final duel of the original series, but he also has a better card pool than his other self.
Ironically, a reason why Yugi is such a great duelist to grind against is because he has a card that makes grinding much easier; Union Attack. This is the key card in a popular farming deck which is needed for the deck to work. Not only that, but you have the Magnet Warriors which are a decent deck for lower-level play that can be buffed into top tier when getting the Electromagnet warriors from booster packs.
5 Avoid: Rex Raptor (DM)
Much like his fellow low-level villain in crime, Rex Raptor's drop cards are pretty awful. Although he isn't quite as bad as Weevil, the monsters Rex drops are among the worst.
When the best monster in the drop list is Black Ptera, you know you're in for a rough time. While there is some halfway decent spells/traps like Big Evolution Pill and Hunting Instinct, it's not enough to make it worthwhile.
4 Farm: Dr. Crowler (GX)
Sometimes, you just want to summon a giant monster and mow through your competition with giant machines. If you want to do that on regular, you need to farm Dr. Crowler.
With staples of the Ancient Gear deck like Ancient Gear Golem, Ultimate Ancient Gear Golem and Ancient Gear Castle, you can make a pretty solid deck just out of drop cards from Crowler. While you're going to need newer cards of the archetype to be top tier, this is definitely a good starting package.
3 Avoid: Syrus Truesdale (GX)
Poor Syrus, always in the shadow of his older brother Zane both in the anime and Duel Links. While we'll get into Zane a bit later, let's deal with Syrus right now.
While there are tons of Roid cards that Syrus can drop, it doesn't change the fact that the Roids just aren't a good archetype. Thus it doesn't matter what Roid cards in his drop pool, they're all going to be worthless.
2 Farm: Zane Truesdale (GX)
On the flip side, Syrus' brother Zane has a few cards in his drop pool that are definitely worth your time.
It doesn't happen often, but there's actually good cards from two archetypes that you can nab from Zane. On the Cyberdark side, we have Cyberdark Cannon and Cyberdark Edge which are solid cards in those decks and on the Cyber Dragon side, we got Cyber Dragon Zwei and Proto Cyber Dragon which are a couple of useful drops.
1 Avoid: Chazz Princeton (GX)
We're sorry Mr. Princeton but we will not be Chazzing it up in Duel Links. Why is that? Well quite frankly, your card drop list is kind of thrash.
Like Zane, Chazz' drop pool has a combination of two archetypes: the Armed Dragon cards and the Ojamas. The problem here though is that while the Ojama cards can be fun to troll opponents with, you can get most of their cards from just leveling up Chazz himself. And for the Armed Dragons, well they've never really been relevant at all. So with all that, we gotta pass on Chazz.
