Been playing Inheritance ladder, peaked at top 10. On paper, I think the idea for Inheritance sounds really cool and prone to lots of creativity, but in practice, there are only a few viable playstyles (stall, semi-stall, weather HO, regen balance), and even then you're kinda forced to run the same stuff every time (for stall you need Sheer Force "check" + Sun check + Rain check + Xatu mon + Regen Core + Zarude check + Unaware mon, which boils down to the same 10 or so mons every time). I think there are serious problems concerning the meta and stuff should go, but before I say that, I would like to post my team.
IIIIIIIIIIIII
Very simple team. You kinda just cover everything with your regen core while spamming KOff. Blissey + two Fire resists check Sun well enough, but if you really want to hard counter it, Flareon!Tapu Bulu is a nice pick that does the same thing Fini was trying to do. I like Wooper!Magearna for checking annoying QD users or Triage mons. Kinda loses to funny Zygarde inheritors and Marowak-A inheritors, but everything else should be fine. In fact, most of the times I recently lost were due to either crits, some other hax, or random Clefable inheritors with a Fire STAB and Calm Mind. This team is so popular I have begun seeing other ladder players with high ELO specifically counter-teaming this team, which I think speaks to how good it is.
With that being said, time for stuff I think should go.
Would like to jump on the Ban SF train. None of these mons have any switchins. Just from Nidoking, BoltBeam + Earth Power + Fighting move of choice covers the entire meta except for...Emogla!Celesteela, and the only reason it's viable anyway is because of Sheer Force. Tauros has the same problem except it gets CC to tear through Blissey faster. Mawile gets the perfect physical and special movepool to pick and choose its counters, and after TPunch + IPunch (Play Rough is honestly unnecessary, Ice Punch already hits everything), it has a choice of SD, Psychic Fangs, and Fire move of choice to trash all but dedicated counters. I think it's SF that's the problem and not these 3 because all the other SF users have solid movepools. Nidoqueen is literally the same movepool that Nidoking has except with TSpikes, Darmanitan has an expansive special movepool with Flamethrower + Psychic + Fighting move of choice, and even something like Druddigon has insane coverage. SF forces normally unviable sets to just check them, and the effect it has on the metagame is unhealthy and way too warping.
Before I started laddering, I didn't think Regen was a problem. Now? I will physically fight to remove it from the tier. It's different than SF that, while it's still dumb, it's dumb in a worse and ultimately detrimental way. At least SF is fun to use. I find no enjoyment in constantly switching out for 100 turns until we can draw. Of course, Regenerator has other problems besides the subjectivity of fun, such as weird Koffing inheritors with NGas + Wisp + Infestation build for the sole purpose of removing Regenerator mons, which I find to be unhealthy, but banning Regenerator would make the tier widely more accessible imo. It would be demoralizing to a new player to find that the best strategy is either to stall for 100+ turns or build to beat stall while leaving yourself open to other matchups. I've seen some rambling about Magic Bounce also being broken, and while I can see it, I think Regenerator is really what enables Magic Bounce to be so good, and vice versa. Both would probably still be good without the other, but I think Regenerator is easily the dumbest of the two and needs to go. If Magic Bounce is still dumb after a Regen ban, then we can talk about it, but for now I'm against (btw free Sableye, he did nothing wrong).
Garchomp may possibly be too much for the meta. Zygarde sets are absurdly dumb, especially SubGlare ones. They have enough bulk to tank a Night Shade, cripple a switchin, and set up on whatever the hell it wants because nothing is taking a boosted Thousand Arrows. Only the most physically defensive resists, like Persian-A!Tangrowth, can even stand up to it, but nothing that can switch in and take hits can threaten it back either. Zygarde!Garchomp also forces way too many guessing games because of what set it might be. Is it SubGlare, or Band, or DD, or Waves Trapper? Who knows? Each of them is built to beat its very few checks, and while it obviously can't use all of them, simply the threat of one and how hard each of them hits. If it was just Zygarde I would be up for a Zygarde donor ban, but Haxorus sets really push it over the edge for me. It gets access to Poison Jab, meaning those physically defensive Grasses that beat Zygarde sets simply fall. I think Garchomp is really dumb, can easily break past all of its checks, and is just kinda broken.
EDIT: Been playing more with Zygarde inheritors and I think a Zygarde donor ban is necessary. Even without Garchomp, stuff like Lando-T and Excadrill can fire off drawbackless Thousand Arrows and chunk everything, while mons like Hippowdon can abuse Coil + TArrows as a bulky win con. Garchomp is still dumb because Haxorus!Garchomp still kinda breaks teams effortlessly, but I wouldn't be mad if Zygarde donoring left as well.
I don't want it gone yet, but is it possible to start talking about weather in general? Drizzle and Drought being able to be slapped on any mons, combined with potent abusers such as Charizard!Chandelure, Venusaur!Lando-T, and Barraskewda!Urshifu-R might be too much. I think Drought is much worse than Drizzle because of how few Fire resists are in the meta (there are 7 Fire resists out of 22 mons from A- to S, and 3 of those are running offensive sets, so realistically only 4 Fire Resists) and even fewer immunities (there are 4 Flash Fire mons on the entire VR, and they're either not put first or running Intimidate), and how much of a nuke V-Create is, 2HKOing stuff like Tapu Fini or Toxapex after Rocks under Sun. Drizzle isn't as bad imo, but could still be problematic in the future because automatic weather and popular abusers are strong. I haven't seen a level close to the nuke V-Create is, so they're more centered around Flip Turn until it finds a good MU. Sand Stream and Snow Warning aren't even close to broken, but there's some good room for experimentation.
Finally, would it be possible to separate the ban list of banned Pokemon and donors? I find it very hard to believe a donor of Chansey would be broken, especially considering Blissey sets work just fine. And I think that mons such as Toxtricity could work even if they weren't allowed to inherit from themselves. Of course, this would impact a limited number of mons, but I find it weird that mons are unable to be used because of one quality and not the other.
Thanks for reading!
