First off disclaimer, this is not a review for every single card, this is for the cards that I feel will impact and change the meta. Everything is my opinion. Shoutout to BuddySpoiler for their consistent hard work and effort over the years (5 years now if i'm not wrong)
Time Dragons
First off is the new flag Overgod 0. While it is a strong win con on it's own, there is huge commitment to the deck space when playing this card. This is because early in the game from Turn 1-4 it is a dead card in your hand with no value, moreover if you want to play this as a win con then it'll mean adding consistency cards for this which also adds to the already constrained deck space. This is a tough choice over Lost World, and I have yet to see which is the better option. Don't get me wrong, this is a strong card but is it game breaking? The answer is no.
Time Dragons have so much draw power to the point they can deck out on their 3-4th turn, that's how crazy it is. If the game drags because your opponent is controlling your gauge and preventing you from going into Lost, you realise that you end up losing to deck out. This new deck refresh card is amazing by itself and it solves a huge problem with Time Dragons, moreover this one card can refresh and reset yourself. Amazing ability, however the requirement of being able to use if only at 4 reverse makes it less appealing to play as it is usually a dead card.
Spell null for Time Dragons, seriously? Yeah Time Dragon has gauge issues early on in the game so it might not be that annoying. However giving a spell null to the most consistent deck in the game is a no go. Definitely a very strong card.
Trying to filter to make your deck more consistent? Enter the Omega. Well this card is extremely strong, however it's extremely susceptible to ability null which makes it a feel bad. Moreover having more than 1 copy at any given time is a feels bad moment. The effect is extremely strong, plussing 2.5 card value which is crazy strong.
Time Dragon always lacked a proper way to restand their cards and now they have something to use. Moreover, this is such a flex card that you can use for many situations, both defensively and offensively. The reduce damage for the turn is extremely strong. As the game drags on this card's power level only rises.
ES is pretty much one of the main reasons why Time Dragon is going over the top. A protection card from everything except bounce. The kicker is the 1 draw if you target 2 cards. This is not a once per turn effect thus you can afford to play 4 since on a technicality this is a free trade off.
Garga
Probably the best Garga, a single card that wins you games. Super offensive and the ability null protection is so crucial against the current meta. However if you miss the RRR spell or lack any Garga's in drop this card becomes less strong immediately and the deck has no offensive pressure. Well hello Giga Howling Crusher for 9-10 damage. FTK?
This is the reason why the matchup against Time Dragon is not as bad as before. This is because this weapon has innate 2 souls which prevent it from being sent to the bottom deck by Time Ruler provided you have Garga on board. Free protection to your board as well. What's not to like?

Genesis Dragons
Like what? It's already so hard to clear Bigbang in the middle and we have a way to call more? A draw with additional soul and the ability to call more without paying the call cost. This card is nuts.
New left and right that can be called once your current one gets cleared. With these new left and right they offer full all round protection for your board. The triple attack alone is insane as well. These 3 simple cards has propelled this deck to the spotlight in Japan recently in the Musashi Cup, I would keep an eye out for this dark horse deck.
Horus
Horus always had the issue of keeping their board sticky, especially the set spell and the monsters. With this card now it is so much more easier, pressuring the opponent more as well in the process, killing two birds in one stone both offensively and defensively. The added check top 4 effect that lets you add any Legend Dragon card is extremely strong because you can find you Luucy and Kifu from it. Going first has never felt better as a Horus player.
A super sticky item that has triple attack and a way to restand your entire board along with your buddy zone? Sign me up, with this card the deck has so many more ways to abuse Magma Horus to it's fullest potential. Horus is coming out of this set as a strong contender for Tier 1.
You might be thinking why is a Messiah Arms card doing in here for Horus? Well the card's effect is not limited to only Messiah Arms, therefore most people opt to run this at 1 copy just for the effect of the check top 2 and a free negate after. Super strong.
Horus, like Time Dragon has insane draw power and with that you usually lose to yourself if you are unable to win the opponent. However, now with this you have a deck refresher, moreover you can add any Legend Dragon card form drop to your hand. Meaning Luucy. Yes Luucy is broken.
Phantom Thief Draco
A 10/10 card, a new card to search for your Maurice or set spell. With this you can afford to run less copies of Maurice and set spell, moreover the most important part is the Holy Magic synergy. Well that and the ability to retrieve back your Harry in drop along with your important monsters.
Another way to add Magical Treasure, a sticky body and free burn? Yes Yes Yes
So how's the meta looking?
I have left out older decks and collab decks as going forward, collab decks will always be considered Tier 1.5 simply due to their nature. Going forward this is the primary focus of the meta going into Team League. As you can see, the format now is more stable compared to S-BT07 with more decks in Tier 1. Now any deck in Tier 1 has more than 50% chance to win Time Dragons provided they go first. So don't think that Time Dragons is broken
