Rock Tomb

Type

Rock

What it does

Has a 100% chance to lower the target's Speed by 1 stage.

At 60 base power it is the 30th strongest of the 39 damaging physical moves that appear in this format.

Who carrys it

19 of the 277 Pokémon measured on the Regulation M-B ladder carry Rock Tomb. The one that matters most is Garchomp, which is on 32.2% of teams and carrys it on 5.4% of its sets. The full list is above, ordered by how much of the format each one is.

What it hits

As a Rock move it is super effective against Bug, Fire, Flying and Ice, resisted by Fighting, Ground and Steel. 5 other Rock moves appear in this format: Rock Slide, Wide Guard, Power Gem, Ancient Power, Head Smash.

Who could and does not

98 Pokémon legal in this regulation can learn Rock Tomb at all, against the 19 that actually bring it. The gap is the interesting number: it is the set of Pokémon that have the option and decline it. The most-played of those are Kingambit, Archaludon, Arcanine-Hisui, Torkoal, Kommo-o and Glimmora — each of them measured on the ladder, each of them leaving this move on the shelf.

How concentrated it is

Across the ladder, Rock Tomb accounts for an expected 0.03 of the six slots on an average team, which makes it the 91st most-brought of the 121 moves this format runs. 53% of that comes from Garchomp alone, so it is really one Pokémon’s move rather than the format’s. Its carriers are mostly Ground (5), Fighting (5) and Rock (3).

Where these numbers come from

Usage is Smogon's published statistics for the Regulation M-B VGC ladder, and the description is the one shipped in the Pokémon Showdown data set. Both are regenerated on every build rather than written by hand, so this page follows the format instead of trailing it. Take any of it to the team builder or the damage calculator.
