Six Samurai has proven itself to be an oppressive deck,making up 68.75% of the Top 16 at MCS17. The deck is consistent at setting up hard to deal with boards such as Legendary Six Samurai - Shi En and either Legendary Six Samurai - Enishi or Six Style - Dual Wield which make countering the deck very difficult. The deck also has strong OTK potential with some builds opting to use Cunning of the Six Samurai. The deck remains un-optimized with the community debating the necessity of Six Samurai United while others drop Six Style - Dual Wield in favor of other disruptive cards and mirror match techs. If you are not playing Samurai, then your build must be tailored to improve the match-up with heavy use of cards such as Cipher Soldier and Sphere Kuriboh. We finally got a powerful Synchro deck, but at what cost?
Six Samurai are undeniably Tier 0. The meta right now is Six Samurai then decks that counter Six Samurai. Every other deck that topped MCS17 had cards mained/sided just to compete with the deck. The fact Koa'ki is maining Cipher Soldier and switching to Sealed Tombs to stop Legendary Six Samurai - Shi En protection is evident of this meta. Another example is Amazoness running Parasite Infestation to prevent a Shi En summon. There is so much being ran just to try and counter the deck and it's still dominating the meta.
Six Samurai have proven they stand alone at the top by not only being the most played deck by far at the recent MCS, but also converting 20 decks to Top 32, despite other decks main decking up to 3 Cipher Soldier to counter them. It's a close call, but Six Samurai might truly be a Tier 0 deck.
There are no Tier 1 decks given the gap in power between Six Samurai and all other decks in the current metagame.
Koa'ki Meiru are demoted to Tier 2 due to a tough Six Samurai match-up. The deck has had to reduce its consistency to incorporate multiple copies of Cipher Soldier and it remains reliant on Diamond Core of Koa'ki Meiru to succeed. Sealed Tombs allows Koa'ki Meiru Ice to deal with a Samurai board while KaibaCorp Bling can search Cipher Soldier or Diamond Core of Koa'ki Meiru as required.
Amazoness remain in Tier 2 due to their ability to compete with Six Samurai at the cost of their other match-ups. The deck now uses Cipher Soldier and can make good use of Lava Golem to clear the Six Samurai board. This is a good pick for the KC Cup if you do not own Six Samurai yet as Koa'ki Meiru remains uncommon on the ladder and you have a good match-up against other common decks such as Ancient Gears.
Amazoness have a fighting chance against Six Sanurai and that's what will surely make them popular. However, going second against a Six Style - Dual Wield set is almost a death sentence. I am expecting this deck to play Sphere Kuriboh moving forward.
Ancient Gears are in a weird spot because the old builds can't compete with Six Samurai. I believe this deck can have a fighting chance with an updated build. On top of that they should have a favorable matchup into backrow heavy decks that main specific hate for Six Samurai.
Dinosaurs are demoted to Tier 3 because they cannot reliably deal with Legendary Six Samurai - Shi En and Six Style - Dual Wield. However, the deck does have useful tools for the meta. Shi En cannot negate Survival's End in the graveyard and Secret Six Samurai - Fuma cannot protect from it due to it destroying two monsters. Evilswarm Salamandra can make good use of discarded Sphere Kuriboh and you should see much less Skull Meister than before. This deck has good potential going into the KC Cup if built correctly.
Dinos could be the dark horse of this KC Cup thanks to the flexibility of the techs they can run and the fact that Survival's End remains one of the best forms of removal in the game which also happens to bypass Secret Six Samurai - Fuma's graveyard protection.
Dinos struggle vs Six Samurai and because their engine is relatively big it makes it harder to put techs in there than in decks like Amazoness. I think Tier 3 is a good spot for them but their position in the meta is definitely not good, they might fall off completely in the future.
Masked Heroes are removed from the Tier List after over one year of relevance. Unfortunately, the deck struggles to deal with Six Samurai's negates and card bounces. Cipher Solider becoming a meta staple is the final nail in the coffin for this equally loved and hated archetype.
Unfortunately Masked Heroes essentially have become collateral damage to the uprise of decks using cards specifically to counter Six Samurai, (most notably Cipher Soldier and Karakuri Ninja mdl 339 "Sazank"). The lack of representation for Heroes is apparent now as a result of this and it is evident that this means that this deck would no longer even remotely be considered viable for competitive events in the near future.
Masked Heroes were made obsolete by Six Samurai and all the main-decked hate for warriors. Time to retire them from the Tier List until a new banlist comes out of course!
Deskbots seem too slow and clunky at times. They are limited by the 3 monster zones, and have yet to prove themselves.
Deskbots had a decent start but as people learned how to play against them they got a lot worse. I don't think the deck can consistently do well vs the meta.
