Dugtrio

Ground · Arena Trap · A tier · 35/80/50/50/70/120 · the format’s premier trapper — the move that surgically deletes Blissey, Tyranitar, and a weakened Metagross/Jirachi so the rest of your offense gets to win.

Typing & role

Dugtrio is a paper-thin pure-Ground attacker with a sky-high base 120 Speed and an Attack stat (80) that barely registers — and none of that is the point. The point is Arena Trap: every grounded Pokemon the opponent has is locked in while Dugtrio is on the field, and Dugtrio is fast enough to move first, status, chip, or kill before the trapped target can react. It is not a sweeper. It is a removal tool — an offensive scalpel you bring in on a specific defensive anchor, eliminate that anchor, and then cash in elsewhere. On an aggressive team it is the single piece that most reliably converts a stall matchup from “grind for 60 turns” into “you have no Blissey anymore, my special attacker wins now.”

Its defensive profile is irrelevant in the way a glass cannon’s is: pure Ground is immune to Electric (it walks into a Zapdos or Jolteon Thunderbolt for free, since Electric vs Ground is 0×), but it is weak to Water, Grass, and Ice (each 2× vs pure Ground) and dies to essentially any neutral hit on its 35/50 frame. You never switch Dugtrio into an attack. You bring it in on a forced switch, on a double, or after a teammate faints, and you make it earn its slot in the one or two turns it lives.

The hard rule that defines how you build around it: Arena Trap does not trap Flying-types or Levitate users. Skarmory, Salamence, Zapdos, Aerodactyl, Gyarados, Charizard, and Levitate Gengar/Claydol all freely switch out of Dugtrio — and Earthquake can’t even touch the Flyers (Ground vs Flying is 0×). Dugtrio traps what is grounded: Blissey, Tyranitar, Metagross, Jirachi, Snorlax, Magneton, Heracross, Forretress, Celebi, and the like. Knowing that list cold is the whole skill of piloting it.

Why it matters to aggressive offense

The defensive backbone of ADV — the wall structure every aggressive team is trying to break — is held up by a small number of grounded anchors, and Dugtrio removes them by hand:

• Blissey. The special wall that single-handedly blanks your Suicune, Starmie, Zapdos, Jolteon, Gengar, and Calm Mind sweepers. Dugtrio traps it and removes it with Earthquake + Beat Up (more on the Beat Up mechanic below). Take Blissey off the board and every special attacker you own immediately gains a clean win condition. This is the marquee interaction and the reason Dugtrio is A-tier.
• Tyranitar. Sand Stream, Crunch, Pursuit, Choice Band Rock Slide — TTar is the glue of half the ladder. Dugtrio’s Earthquake hits Rock/Dark for 2× (Ground is super effective on the Rock half), and Dugtrio outspeeds and traps it, so a weakened or even healthy Tyranitar gets deleted before it can Pursuit your Gengar/Starmie out. Killing TTar also turns off the sandstorm that was chipping your team.
• Metagross / Jirachi. The premier Steel pivots both eat 2× from Earthquake (Ground hits Steel for 2×). Dugtrio can’t always OHKO a full-health Metagross, but it cleans up a chipped one and traps it so your team isn’t perpetually walled by a Meteor Mash spam-bot or a Calm Mind Jirachi. Removing the opposing Steel also frees your own physical attackers.
• Magneton. The most one-sided trap of all: Magneton is Electric/Steel, and Earthquake hits both halves for 2× each — 4× super effective — so trapped Magneton is an instant, guaranteed kill. If their DragMag relies on Magneton to trap your Steel, Dugtrio answers it directly.

In every case the value isn’t Dugtrio’s damage output, which is mediocre — it’s that the trap guarantees the kill lands on the right target. A normal attacker threatens Blissey and Blissey switches to Skarmory; Dugtrio threatens Blissey and Blissey stays in and dies. That guarantee is what an aggressive team pays a teamslot for.

Key sets

Choice Band trapper

The one set that matters. Choice Band is on virtually every Dugtrio that hits the ladder (over 99% of them), because the whole job is making a single hit count: you trap the anchor, and the Band turns Dugtrio’s mediocre base 80 Attack into a number that actually deletes a chipped Steel, Tyranitar, or Magneton outright. The spread maxes Speed (base 120, the move that lets it act first against the trapped target) and Attack, with the 4 left over dumped into Special Defense.

Dugtrio @ Choice Band
Ability: Arena Trap
Adamant Nature
EVs: 252 Atk / 4 SpD / 252 Spe
- Earthquake
- Hidden Power Bug
- Aerial Ace
- Rock Slide

Earthquake is the kill button on every grounded Steel, Rock, and Magneton — it’s the reason the trap exists, hitting Metagross/Jirachi (Steel) for 2×, Tyranitar (Rock/Dark) for 2×, and Magneton (Electric/Steel) for 4×. Hidden Power Bug is the second-most-common move on the set and chips the Psychic/Grass and Dark anchors — it hits Tyranitar for 2× on its Dark half and Celebi for 4× (Bug is super effective on both Psychic and Grass). Aerial Ace is the near-universal coverage slot for the trapped Fighting-types: it hits Heracross and Breloom for 4× (Flying is super effective on both Bug/Fighting and Grass/Fighting) and never misses. The fourth slot is the flex — Rock Slide is the highest-value choice for an aggressive build, adding damage against the Flyers you can catch on the switch (it’s coverage, not a trap — Flyers aren’t trapped) and a second answer to a chipped Zapdos/Salamence that stays in. The two slashed alternatives, Beat Up and Sunny Day, are the Blissey-removal and sun-support options respectively; on offense, Rock Slide’s raw coverage wins the slot.

Note the nature is the only real flex: Jolly is also standard, but since the spread already runs 252 Speed and Dugtrio’s base 120 outpaces the entire relevant metagame either way, Adamant squeezes out the extra Attack that turns “barely fails to OHKO” into a kill on the borderline Steels.

On Blissey. The folklore line is “Dugtrio uses Beat Up to remove Blissey,” and on the rare Beat Up build it does — in Gen 3, Beat Up strikes once per healthy, non-statused party member, each strike calculated from that member’s base Attack (so the Choice Band boost is irrelevant to it), and against a trapped Blissey a full party’s worth of hits plus chip wears it down. But the standard ladder Choice Band set above doesn’t run Beat Up — it traps and pressures the Steels and Fighters with Earthquake/Aerial Ace and leaves Blissey-removal to a dedicated Beat Up variant or to a teammate. Plain Earthquake into a healthy Blissey (neutral, Ground vs Normal is 1×) does not get there.

How an aggressive team uses it

Dugtrio is a setup-enabler, not a setup sweeper — you spend it to make someone else’s sweep inevitable.

1. Identify the anchor your wincon loses to. If your win condition is Calm Mind Suicune or a special Zapdos, that anchor is Blissey. If it’s a physical sweeper, it’s often Skarmory (which Dugtrio can’t trap — plan around that with Magneton or a Taunt lead instead) or a grounded wall.
2. Bring Dugtrio in safely. It can’t switch into attacks, so it comes in on a forced switch, a slow pivot (a fainting teammate, a Baton Pass), or by hard-predicting a passive turn. Crucially, it switches into Electric attacks for free (immune), so a Zapdos/Jolteon clicking Thunderbolt is a clean entry.
3. Trap and remove. Earthquake the Steel/TTar/Magneton; Aerial Ace the trapped Heracross/Breloom. For Blissey specifically you want the Beat Up variant (the standard Choice Band set above doesn’t carry it). Dugtrio’s base 120 Speed means it moves first against everything that isn’t Scarf-less faster (there are no Choice Scarves in ADV — see mechanics §1), so the trapped target rarely gets a meaningful turn.
4. Cash in. With the anchor gone, your special core sweeps. The ZapDug and special-Spikes structures are built on exactly this loop — Zapdos applies pressure and forces switches, Dugtrio traps and kills Blissey, and the special attackers clean up a team that no longer has a special wall. See common cores and sample teams.

The mental model: Dugtrio is a one-time “delete this Pokemon” button with a Speed tier attached. You don’t keep it healthy for the late game — you spend it the moment removing its target wins you the match.

Counters & checks

Because Dugtrio is so frail and so narrow, “checking” it is mostly about denying the trap:

• Anything Flying or Levitate. Skarmory, Salamence, Aerodactyl, Gyarados, Charizard, Zapdos, and Levitate Gengar/Claydol are simply not trapped and laugh at Earthquake (Ground vs Flying/Levitate is 0× or no-effect). Building your defensive anchor on a Flyer is the cleanest immunity to Dugtrio entirely.
• Out-damage its frame. Dugtrio has 35/50/70 bulk; effectively any neutral STAB, priority, or super-effective hit from a Pokemon that survives the turn kills it. A Suicune Surf, Starmie/Gengar Ice Beam, or any Breloom/Heracross Fighting-resisted-but-still-strong hit ends it — Water, Grass, and Ice all hit pure Ground for 2×.
• Don’t let your anchor get trapped low. A healthy Metagross or Tyranitar often survives a single Earthquake and can KO Dugtrio back (TTar Rock Slide, Metagross Meteor Mash), so the defensive player’s counterplay is to keep those anchors above the OHKO threshold and never let Dugtrio in for free. Sandstorm chip from Tyranitar also pressures Dugtrio every turn it’s out.
• Lum Berry / status timing. Beat Up only counts healthy, non-statused party members, so a team carrying status (burn from Will-O-Wisp Gengar, paralysis spread) quietly cuts the number of Beat Up hits Dugtrio gets on your Blissey — a subtle but real way to blunt the trap.

For the aggressive pilot, the takeaway runs the other way: your job is to remove the opponent’s Dugtrio cheaply (it dies to anything) while protecting your own grounded anchors from being trapped — and to lean on Flyers and Levitate mons as your own anti-trap insurance.
