The longer something exists, the more likely it is to change and evolve. Card games are not exempted from, this meaning Yu-Gi-Oh! inevitably had to do this to remain relevant. One of the ways Konami did this was to introduce new monster types every so often to add more variety and lore to the many universes found in the franchise.
Cyberse monsters are one of the newer monster types introduced in Yu-Gi-Oh! coming out in 2017 with the announcement of a new anime in Yu-Gi-Oh! VRAINS. As the newest kids on the block, Cyberse monsters had a lot of anticipation prior to release due to the unique theme surrounding the monsters. With that being said what better way to show appreciation to said monsters than to look at some of the best.
10 Knightmare Corruptor Iblee
Released on January 18th in the OCG and May 3rd of the same year in the TCG, Knightmare Corruptor Iblee was one of the early cards to synergize well with Link monsters. It would also prove to be a bit of a nuisance in the early days of the Link era as many players didn't always have a way to deal with the monster.
While Iblee's first effect is good it wasn't always the reason the card was played. The floodgate effect the card has in locking opponents out of special summoning except for Link monster could often yield an instant win in some cases, but as time went on and more viable Link monsters came out players wouldn't have too much trouble dealing with the card.
9 Salamangreat Almiraj
It isn't uncommon for cards to be more popular outside their archetype, but it doesn't always remain this way. As the meta shifts and cards go in and out of the banlist, it's hard to believe a card released in 2019 has continued to be a mainstay of so many unique decks to this day.
Salamangreat Almiraj is great specifically because of its summoning requirement. Often this can be a death sentence for some cards, but because it's so "generic" it allows the card to slot into so many decks that it isn't uncommon for Almiraj to be the only Cyberse monster in the entire decklist.
8 Firewall Dragon
It wasn't all that long ago when Firewall Dragon was terrorizing the metagame with numerous OTKs and infinite loops. The card became so omnipresent that almost every meta-viable deck looked for a way to incorporate the card into their strategies. Eventually, the card had to be banned and would soon receive an erratum before coming off the banlist.
While its reign is definitely over it is far from a mediocre card. Nowadays, Firewall Dragon sees healthy play in decks mainly focused on Cyberse monsters, specifically those that look to special summon a lot, such as Salamangreat decks.
7 Cyberse Gadget
If versatilely is the name of the game then Cyberse Gadget has that on lock. As one of the best starters to almost any Cyberse deck combo, the card boosts immense synergy with so many different decks it's hard to ignore.
Thanks to fantastic Spell cards like Cynet Mining, Cyberse Gadget is capable of being a one-card Link-2 summon, which is an extremely impressive distinction. With other combo extenders such as Link Devotee and Link Disciple, Cyberse Gadget's stock continues to be at an all-time high even in today's metagame.
6 Dotscaper
Don't let the cute cart artwork be deceiving as Dotscaper is a fierce monster that is one of the key playmakers for most if not all Cyberse focused decks. This has more or less been the case since the cards release in 2017 and that doesn't look like it will change.
This card is one of the best playmakers because it can summon itself back to the field twice and from two different methods. While this is limited to once per duel for balance reasons, it allows Dotscaper to be an amazing combo starter and essential in decks that need one more summon to finish their plays.
5 Mekk-Knight Crusadia Avramax
One of the hallmarks that makes a good boss monster is "protection," high stats, and a reasonable summoning condition. Thankfully Mekk-Knight Crusadia Avramax is all this and so much more with the added benefit of being quite balanced.
Not only does the monster slot into many decks and numerous playstyles, but it also has one of the best removal effects in the entire game. Right out the gate the effect is easy to activate, it does not target, and the fact that it shuffles a card is significant because this bypasses numerous common floating effects.
4 The Arrival Cyberse @Ignister
The @Ignister archetype has a lot of personality and flare, but what many forget is that it also includes one of the strongest boss monsters of any archetype in The Arrival Cyberse @Ignister. Its strength can easily be identified in its useful removal effect and potentially high attack stat that is dependent on the number of monsters used for its summon.
Without a doubt, the best part of the card is the fact that it is unaffected by other cards' effects. This means even the controlling player is unable to use effects on the card. For added context, this effect is so rare that only 34 other cards in the entire card pool share this exact effect.
3 I:P Masquerena
Initially, a player may not put too much stock into Link Summoning on their opponent's turn since it isn't a common option. However, once the plays start to become more apparent...any player of any level will realize how powerful this effect is especially when it's a quick effect.
Players that utilize this effect of I:P Masquerena will often go into Knightmare Unicorn to disrupt an opponent's plays or another boss monster to make their board even more difficult to deal with. An often forgotten and unappreciated effect I:P Masquerena has is when it is used for the Link summon for another Link monster that monster cannot be destroyed by an opponent's card effects.
2 Topologic Gumblar Dragon
If Topologic Gumblar Dragon wasn't banned in the OCG and limited in the TCG it would most definitely be running rampage as one of the most disruptive and frustrating cards in the metagame. The card's legacy is so notorious that many Yu-Gi-Oh! players question why it was even printed.
Gumblar Dragons got excellent stats, an easy summoning condition, it forces the opponent to discard multiple cards per turn and will do burn damage to add insult to injury. Even without protection and/or a floating effect, this card may go down as one of the best Cyberse monsters to ever be released.
1 Accesscode Talker
If any card is deserving of being the best Cyberse monster in Yu-Gi-Oh! it has to be Accesscode Talker. It checks all the boxes that are required to be a fantastic card with the added benefit of being easily accessible which wasn't always the case for many cards on this list.
As of early 2023, the card is in the top 10 most-used cards in TCG/OCG and Master Duel. This isn't all that surprising when players consider the card has high stats, non-targeting removal, absurdly easy summoning condition, and other cards cannot respond to its effects. With a resume like this, it's hard not to consider Accesscode Talker as the best Cyberse card in the game.
