I think if there's anything that can be questioned in the A-Rank, it would be Tirtouga
"Reserved for Pokemon that are outstanding in the LC metagame and can sweep, wall, or support the majority of the tier. These Pokemon require less support than other Pokemon to be used effectively and have few flaws that can be overlooked when compared to their outstanding traits."
Let's zoom in on the second sentence there. I believe that Tirt's flaws are not easily overlooked, as their weaknesses are just exposed in the current metagame. Most people know that I don't like unreliable and volatile strategies, and prefer safer mons cuz I don't have that much swag. Anyway, let's go into Tirt's flaws, and why they are easily exploitable in the metagame.
ALRIGHT TIRT
- TIRT LOSES TO LOTS OF STUFF, THAT'S NOT EASY TO OVERLOOK
- TIRT IS EXTREMELY RELIANT ON HIS ITEM
- EVERYONE JUST SWEEPS BETTER THAN HIM
- HIS DEFENSIVE SET HAS NO RECOVERY
- PUMPKABOO
- LIKE SRSLY FUCK STATUS
Alright let me start off and say I really liked and continue to like Tirtouga. Tirtouga does a pretty ok job in doing what it has to do, and that rock typing is really nice against Flying-types, it also doesn't lose to Diglett so its a nice answer to the FletchDig combo. Tirtouga also has a solid matchup against Archen, which is played almost as often as LC itself. However Tirtouga often does not pose a large threat to a team, because of how many checks there are to it. Out of the pokemon from S to A+ Rank, 6 out of 10 are excellent at threatening Tirt. If you look down to A rank, you will find even more pokemon that threaten Tirtouga. The pokes that wreck it hard are ran on almost every team, especially since most teambuilder's dicks are bulking up for Timburr recently.
Next would have to be that it is reliant on its item. If you run the defensive set, Knocking off its BJ makes it really fkin hard to setup, since it could get wrecked by priority (unless you're a mindgame god with Aqua Jet, like TUO) Berry Juice is also easily nullified most of the time after Rocks are setup, since its Sturdy will not be usable. It's Eviolite set has problems as well. When it's evio gets knocked off, it is much worse at taking hits, and all Tirt(defensive) really contributes outside of Rocks for a team is 70% chance of burning the opponent with Scald. While the 70% chance is nice, Eviolite tirt gets easily worn down by hazards, status, and just repeated attacks at it due to its lack of recovery, minimal offensive presence (at least with evio ver.) and its typing. This is even more relevant when it gets Knocked off, which is shitty. Tirt really hates Knock off.
Metagame trends like Pumpkaboo and RestTalk Skrelp make it really hard for Tirt to do shit, especially when Pumpkaboo can make sure hazards stay on the field. Tirtouga definitely finds its place on a team, and belongs in that A area, but I believe it is in the lower area of A-rank, which is well, A-.
I know it has been discussed a bit, but I just wanted to put in my opinion I guess
EDIT:
I have proof that i'm not a biased (BAN ME PLEASE) vs Tirtouga
I would also like to nominate my formatting skills to S
