Pokémon Champions: How to Use Lycanroc in Regulation M-B – Off-Meta Build Guide

Lycanroc is still legal, still unnerfed, and still better than its reputation in Regulation M-B — but M-B made the off-meta Endeavor set noticeably harder to pilot. If you want the consistent version, run Dusk Form with Tough Claws and the standard shell of Rock Slide / Protect / Accelerock / Close Combat. If you want the game-stealing gimmick, build Sand Rush with Focus Sash, Endure and Endeavor behind a Tyranitar — and accept that M-B added three new Ghost-types that blank Endeavor outright.

No balance patch, ban or restriction has touched any Lycanroc form. Nothing in the published Regulation M-B rules or the Champions patch notes names Lycanroc at all. What changed is the room it plays in.

Where the format stands in July 2026

Regulation M-B is the live ranked regulation, and it is a big one. It inherits the whole M-A roster and adds roughly 22 more species plus 16 new Mega Evolutions, including the two Champions-original Megas, Mega Raichu X and Mega Raichu Y. Per Serebii’s regulation page, ranked M-B is a Doubles ruleset with teams of four to six at Level 50.

Worth knowing the stakes: Champions is now the official software for the 2026 World Championships, replacing Scarlet and Violet VGC. The ladder you are testing Lycanroc on is the ladder that matters.

Pick the form before you build anything

This is the step players rush and it matters more for Lycanroc than for almost anything else. Lycanroc’s form is locked at evolution and cannot be changed. Your whole plan starts here.

• Dusk Form — Tough Claws. The stable, tournament-shaped attacking set. Better default for M-B.
• Midday Form — the Sand Rush option, for the Focus Sash / Endeavor build. Higher ceiling, far less self-sufficient.
• Availability: the Roster Ranch rotation that offered Dusk Form during the M-A window (8 April – 17 June 2026) has closed. Lycanroc (Dusk) remains legal in M-B, and Pokémon HOME transfer is the reliable route if you already have the correct form from an earlier title. Check the current Ranch rotation before assuming you have to transfer.

Double-check the form before you spend resources. Lycanroc is one of those Pokémon where “close enough” costs you an entire build.

The Dusk Form build most players should start with

Dusk Form, Tough Claws, Rock Slide / Protect / Accelerock / Close Combat, Focus Sash. Tough Claws is the leading ability choice in usage terms and has been ahead of Sand Rush since launch, and that move package is popular because it does four jobs in four slots.

• Rock Slide is the near-universal pick because spread damage is what makes a fast attacker matter in doubles. Single-target contact damage alone is not enough.
• Protect is not optional. Lycanroc is fragile and often needs one turn to let a partner set Tailwind, land Fake Out, or bait an attack.
• Accelerock is the reason opponents cannot safely sit at low HP against you. It is the cleanest priority finisher Lycanroc gets.
• Close Combat is the coverage that stops it folding to Steel- and Dark-types — and M-B put a lot more Steel on the board.

Focus Sash is the safest starting item while you learn the damage ranges. Once your team already supplies speed control and positional support, you can experiment, but Sash keeps Lycanroc useful in messy games.

The Sand Rush build, and what M-B did to it

Max Attack, max Speed, Focus Sash, Sand Rush, and a move package built around surviving one hit and converting that into a forced trade: Endure / Endeavor / Accelerock / Close Combat. Some teams swap one slot for Rock Slide, but the full trick package is where the pressure comes from.

• Focus Sash guarantees Lycanroc gets to act at least once against a bigger hit.
• Endure is a second route to the 1 HP state when Sash has already broken or you are reading a double-target.
• Endeavor drags a healthy target down to Lycanroc’s current HP. That is the whole reason the set creates panic.
• Accelerock finishes the target before it recovers tempo.
• Close Combat keeps Lycanroc from being one-dimensional against Steel and Dark targets.

The new problem: M-B is full of Ghosts

Endeavor is a Normal-type move, so Ghost-types ignore it completely. That was always the set’s weakness. Regulation M-B made it substantially worse by adding Gholdengo, Annihilape and Houndstone to the legal pool.

That is three new, genuinely playable Ghost-types, and the first two are not niche picks. Gholdengo is Steel/Ghost — it resists Rock Slide, resists Accelerock, and is immune to Endeavor, which means your entire trick package does nothing to it. Annihilape is Ghost/Fighting, immune to Endeavor and perfectly happy to click a Fighting move back at a Focus Sash user. If either is in team preview, the Sand Rush set has already lost half its value before turn one.

The practical adjustment: check team preview for Ghosts before you commit to the Endeavor line, and be far more willing to lead the Dusk Form set instead. Against a Ghost-free board the Endeavor set is as strong as it ever was. Against Gholdengo it is a wasted slot.

The sand partner question

Sand Rush is not theorycraft — it needs sand on the field, and Tyranitar is the obvious source. Tyranitar is confirmed legal in M-B, as is Hippowdon if you want a bulkier setter that does not draw the same attention. Before locking a Mega slot, check the in-game legality filter for Mega Tyranitar specifically — the published M-B Mega list names the newly added Megas and does not clearly confirm it, so verify rather than assume.

One correction people still get wrong: Tailwind helps your team’s speed control but does not replace sand. If sand is not up, Sand Rush is doing nothing at all. Tailwind is a backup layer, not the engine.

Piloting the Sand Rush set without it looking fake

Do not throw Lycanroc into neutral boards and expect the gimmick to bail you out. The best turns are the ones where you already know what the opponent wants to protect. If their bulky attacker is staying in because it survives any normal Rock move, that is when Endeavor becomes terrifying. Once Lycanroc is at 1 HP, even a resisted Accelerock can clean up if your partner chipped the board first.

The biggest trap remains Endeavor into the wrong target. Ghost immunity is the obvious one; multi-hit attacks break the Sash plan, and opposing priority ruins the cleanup turn before Accelerock matters. This set is for reading a single big hit, not for chaotic boards.

Also remember Close Combat is a commitment. It answers Tyranitar and most Steel- and Dark-type threats, but the defence drops usually end Lycanroc’s career as a reusable piece. Treat it as a trade tool, not a midgame button.

What support Lycanroc needs

Lycanroc looks incredible when the team around it creates chip damage and speed certainty, and mediocre when asked to break full-health bulky targets alone.

• Tyranitar or Hippowdon for Sand Rush sets — weather plus a threat that draws respect in preview.
• Fake Out, redirection or Protect cycling so Lycanroc lives long enough to use its priority instead of dying on entry.
• Tailwind or other speed control matters more for Dusk Form than people admit. Lycanroc is fast, not infinitely fast, and M-B added several fast Megas.
• A Ghost answer. This is the new requirement. Something that reliably threatens Gholdengo and Annihilape keeps them off the board long enough for Lycanroc’s plan to work.
• Chip-heavy teammates. Accelerock is a finisher. Lycanroc is usually your closer, not your opener.

The mistakes that make Lycanroc look worse than it is

• Sand Rush without committed sand support. If a reliable setter is not in the team plan, just play Dusk Form.
• Endeavor as a universal button. Three new M-B Ghosts, plus multi-hit attacks and priority, all punish lazy clicks.
• Dropping Protect on standard sets. In doubles that slot often decides whether Lycanroc gets to use its Speed at all.
• Ignoring form permanence. You do not fix this later by swapping forms.
• Expecting it to muscle through bulky teams alone. Lycanroc converts damage and tempo; it does not replace an offensive core.

FAQ

Has Lycanroc been nerfed or banned in Regulation M-B?

No. Nothing in the published M-B rules, the Champions patch notes, or any regulation summary names Lycanroc or changes Tough Claws or Sand Rush. All forms are legal.

Is Tough Claws still the better ability?

For general ranked play, yes — it has led usage since launch and it does not depend on a teammate to function. Sand Rush is a build-around, and M-B’s Ghost additions made that build-around more conditional, not less.

What regulation and season am I laddering in?

Regulation M-B. Season M-3 ran 17 June to 8 July 2026; Season M-4 runs 8 July to 5 August 2026, still under M-B.

How do I get Dusk Form now?

The M-A-window Roster Ranch rotation has ended. Pokémon HOME transfer is the reliable route if you have the form in an earlier title; otherwise check the current Ranch rotation in-game, since rotations change per season.

Does Champions use Singles or Doubles for ranked?

Serebii lists ranked Regulation M-B as a Doubles ruleset with four to six Pokémon at Level 50. Monthly Challenge Series events run their own format, so read the individual event page before building for it.

So yes, Lycanroc is still underrated in Pokémon Champions — in the right context. Dusk Form Tough Claws is the dependable version and where most players should start. Sand Rush Focus Sash Endeavor is the sharper, meaner option when you can build around a sand setter and the opposing board is not stacked with Ghosts. Pick the right form, respect the matchup limits, and use Accelerock as a cleanup tool rather than a panic button.
