So there are a lot of people making bold statements about what is and isn't op right now during the expansion.
But let's ground things a little with a mobalytics article and I'll break down each list and how I feel about it.
https://mobalytics.gg/blog/best-legends-of-runeterra-decks/

A lot of this is gonna seem obvious extra attacks plus sandmen equals double value and double aggression
Rememberance if a bunch of your tokens are dying you get to cast it for free
Rangers resolve as anti wail/ice shard tech
Rock hopper is supposed to synergize with greenfang warden where you get to utilize barrier to challenge, not sure how reliable that is at 2 a piece
Also ancient preparations will probably get cut it doesn't do anything in this list
But everything else look great.
The thing is though we have so many great aggro lists that this is looking B tier right now

I had said that they who nasus would be a great list during announcement season and here it is
A lot of this list looks super flexible I like the baccai spinners here, trade with your opponents champ to enable slay
3 counters to 1 atrocity is interesting, and again we see a lot of confidence in rock hopper which I don't share
Black spear is great I always thought that card was underated, and thresh gets you the box too
I would say this deck has A tier potential

Hey look it's anivia control without the jank, not much else to say
You just stall and stall and stall till your free 8/8's pop out fresh as daisies
Spectral matron is fun, you play it on rekindler or inquisitor and it levels Lissandra
Honestly just super solid S tier stuff here

So it's ledros control without carina, and without the otk potential of concurrent timelines
I don't think this list makes sense honestly, like all you need is like 1 hush play and this deck is done
I think this list is being carried by surrenders, people just get hard controlled and give up

So veiled Temple Thaliyah with Aphelios is a strong mana cheating list
I really like weight of judgement here card is super undervalued I run it as a 1 of in a lot of decks
Goal is pretty simple stack your buffs on one dude and then infernum for overwhelm
You also get your burn dmg from leveled Thalia
The only question is, better than TF Aphelios where you get your free 3/4 challengers
Just having deny might make it better, but it looks weak to aggro I see the fangs going down on 4 and its too little too late
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The truth is though a lot of important lists are absent I believe that there is absolutely a very strong Rekton list out there
I believe that Ash with Leblanc looks absolutely nuts
I think deep should be revisited, along with dragons
The fact a lot of what we are seeing is people just playing shadow isles is not a great sign on the creativity front
and what about Sivr, you can't tell me she's garbage, she has spell shield and quick attack like holly crap
Anyway that's it for me, let me know what you guys think down below.
