Tier 1
TPC Comments
The deck continues the trend of playing Loading... and backrow like Loading... to have an advantage in the mirror, where blocking one zone for a whole turn while also being good cards to chain to Loading... targeting the backrow is huge.
Furthermore people started siding Loading... mainly to have a handtrap against Set! Delta Accel! Tech Genus. D.D. Crow has a lot of targets it can hit if needed like all the Paleozoic Traps in the GY, Loading... , Loading... 's target, or Loading... when it's attempted to be revived by Loading... . The Bonus of D.D. Crow is that it can be looped with Loading... since it is a monster.
Aside from that there is nothing to talk about since Onomat is still the deck to beat in the format
Tier 2
There are no decks in Tier 2
Tier 3

Gaia continues to be the main point of discussion based on how good it is in the format outside of the Onomat matchup, against which every deck needs to draw specific hands. If Onomatoplay received a nerf to make Onomat more inflexible like all the other decks, Gaia would be the best deck in the format (and we'd probably see a rise in Cyber Dragon). At this point I believe we should be seeing more Cyber Dragon and preparing for it in tournaments, since all decks seem to need 3+ card combos (outside Onomat) to play around the best deck, why not Cyber Dragon? It has a good matchup against Gaia and create powerful OTKs with the right hands and will continue to do so for as long as Cyber Style exists.
Gaia may remain at Tier 3 but it continues to undergo small deck building changes each week in order to have stronger matchups across the board. Most duelists have already pushed Loading... into the Side Deck for matchups that can be tough to find lethal in, with some duelists forgoing the card altogether. This is in order to avoid as many bad draws as possible and play one more defensive card than normal. Speaking of defensive cards, there's been a gradual shift away from removal to have a greater focus on defensive cards such as Loading... and Loading... in order to have a stronger matchup against combo decks like Onomat. Just like it has been since its introduction in Duel Links, the reliable Gaia strategy can prove to be too much for many duelists to break through and is expected to perform well in the coming weeks.
Harpies are in this weird place in the meta in the sense that it can beat top decks sure, but the matchups against any other tiered deck seem unfavorable. It is primarily a gatekeeper to backrow decks, rogue decks and decks like Fire Kings which are forced into Loading... turbo and has an awful Harpie matchup. It completely keeps Shiranui on the fringes as well as any other Endless Trap Hell deck that one can come up with. It can successfully side Loading... to help some matchups and flexes its skill in Side Deck formats so it's still formidable but definitely feels weaker than a deck that can play Loading... (in the form of Loading... ) turn 1 should.
