The current meta is very floodgate-dominant (between Loading... , Loading... , Loading... , Loading... , Loading... , and Loading... ), so the Top Tiers consist of decks that can either play through a floodgate or play one themselves.
Tier 1
TPC Comments
Blue-Eyes was decreasing in popularity in the prior meta, but with Phantom Knight's rise to prominence, the deck received its second wind. A deck capable of maining 3 Loading... and 1 Loading... and still play optimally is something notable (Also, Blue-Eyes can play through Loading... /Loading... without much difficulty).
Blue-Eyes move up the Tier List, as it has no bad match-ups aside from Shaddoll (which has had a declining participation as of late). It is also able to set-up solid interruptions going first, break boards going second, and play strong techs like Loading... to counter the other Tier 1 deck.
Tier 2
TPC Comments
Performage is a deck that doesn't excel in any particular aspect. It's a Rank 4 Xyz toolbox with the ability to play through some disruptions (thanks to Loading... + Performage Showtime ) and flood the board (thanks to the aforementioned Skill, Loading... , and Loading... ). The deck's main boon is the ability to reliably establish Loading... , shutting down Phantom Knights.
Shaddoll is strong, Loading... is strong. The deck can not only establish the most powerful floodgate in the game but also protect it. However, the deck has been unable to perform consistently well in the last couple weeks. Their recent showings, and their matchups against Blue-Eyes and Phantom Knights are poor enough to demote Shaddoll to Tier 2 for the time being.
