I’m a massive n00b but enjoying ADV OU a lot. A couple of basic questions:
-Is there any place with info on good leads? I’m currently leading Skarmory but no idea if that’s a good idea.
-Why is Tyranitar so highly rated? I’m using it and sand seems great, but other than that…
Most things everything outspeed it and have a super effective move too. Is its strength in its unpredictability?
1)
https://www.smogon.com/stats/2025-10/leads/gen3ou-1630.txt. You can see the lead statistics on ladder here. Go to the parent domains if you want to customize more.
Broadly speaking though, the meta revolves around tar and zap lead. Zap lead is good into ~ everything but tar. Tar lead is good into zap, neutral into mence and not great into the other common leads (depending a bit on the set but on average). But tar lead is still quite common because a lot of teams want to set sand t1, and/or don't switch well into zap. Leading something weak to zap without a very sturdy check to zap (that is not blissey, owing to the risk of pass to bulky beat up dug teched to trap blissey) is risky because sub pass zap can ruin your life badly.
Skarm lead was very common back in the days before beat up dug was a thing -- and becoming more common again now as zapdug fades somewhat from peak popularity. It definitely does still suffer from its bad zap lead matchup though. You will often see it paired with regice or jolteon or on a super offensive team where it intends to just yolo click spikes t1 and hope to live tbolt or get overpredicted.
2) You mention two of its biggest strengths, setting sand and having huge set variety, which are both undoubtedly part of the story. But the other thing is that tar is extremely bulky (at least when given HP investment which is typical), so while most everything can hit it, very little can one shot it unboosted besides stab fighting moves and it can usually hit back quite hard. It also soft walls a lot of special attackers that either lack power or a boosting move like electric types, blissey, jirachi, etc.
This also brings me to another point which I didn't fully appreciate when I was starting. Dragon Dance Tar is immensely immensely threatening because it outspeeds the whole tier at +2 and can only be reliably stopped defensively by swampert (and to a lesser extent flygon and some other rarely seen options like donphan or whatever). An extremely common way games end in ADV is Tyranitar gets an entry on a mon that can't deny its setup, it clicks dragon dance as opponent switches to a soft check, it dances again and lives a hit or clicks rock slide and gets a flinch --> sweep.
I also just want to add one more thing about setting sand. It is hard for a team to be extremely consistent, i.e. not have any wacky set that just 6-0s you from the start, if you don't have sand. Sand is the thing holding back a lot of things that would otherwise be giga threats like pinch berry reversal/flail sweepers, subcm suicune, curse rest lax (honestly all suicune and lax sets to some extent), rest zapdos, etc. Now, I'm not saying it's impossible -- and there are certainly notable players who load a lot of sandless to success. But for a lot of players they'd rather just load tar which is a perfectly good and solid mon than play GSC lite for 500 turns or randomly get 6-0'd on preview from some cheese.
