I count 2 viable pokemon that have been added to lc, croagunk and snover. The meta will barely change from what it was before sinnoh and the pokemon that were broken before are still broken.
Murkrow is absurdly powerful, having precisely 0 counters in the tier. Maybe you think it can be handled by archen or maybe chinchou.
Archen, 2hkod. Chinchou must rely on resttalk w/ heal bell to stay alive against murkrow. Shaky at best. You could argue nosepass in sand can handle murkrow, but sand is quite hard to mantain and nosepass is pretty bad otherwise. Another shaky answer. Not only is Murkrow unwallabe, it is very hard to revenge kill due to its powerful priority in sucker punch.
Some of the popular scarfers of the tier, not including the ghosts bc they die ofc. The only new mon that changes anything to do with murkrow is snover, which can get off a scarf ice shard for a lot of damage. Even then, locking into ice shard quite sub optimal. Murkrow still annihilates the tier.
Scraggy is also still able to steal games with minimal effort. Here is its new check
meh. Timbur and mienfoo are the best checks, but +1 zen headbutt does a significant chunk and thus need to be kept health/near full. Oh and vullaby gets 2hkod after rocks.
Not a couple checks to misdreavus, a singular check to misdreavus, stunky. An unreliable and unsustainable check. It can't keep switching into misdreavus taking the chip and also has to keep playing the pursuit/sucker punch game with misd. You'd be better off cheking misd offensively, besides stunky is pretty poor outside of checking misd.
So, can we stop this nonsense and not flood the tier with ridiculous threats. Let's move the tier forward, not backwards.
