Lucky Trades are one of the cheapest ways to bring a high-CP Legendary up to battle-ready level. The Stardust cost is cut in half, and the Lucky IV floor of 12/12/12 means every Lucky outcome lands at 80% of perfect IVs (36 out of 45 total) — no catching dozens of copies hoping for a 15/15/15 reroll. Even the lowest Lucky roll sits in the “Great” grade band, which is plenty for Master League and raid use. With the recent Lucky Charm item turning every Lucky Friend trade into a guaranteed Lucky outcome, choosing which Legendary to pour your Lucky Trade into matters more than ever.
This guide ranks the Top 10 Legendaries (and Ultra Beasts) most worth using a Lucky Trade on in Pokémon GO, based on raid utility, max-battle relevance, ML viability, and the long-term Stardust math. Each pick is linked to its individual evaluation page on Doctor Pokégogo, where you can drill into per-form DPS, eDPS, and tier rankings.
How This Ranking Was Calculated
Each Legendary was scored on four dimensions before being ranked:
- Raid utility: Per-type DPS / eDPS using the live Type Ranking data set (PL50 IV15, raid boss HP 22,500 baseline).
- Max Battle relevance: Whether the Pokémon (or its evolutions/forms) has a usable Max Move kit. See Max Battle Type Ranking.
- Master League viability: Stat Product and current usage rate.
- Stardust efficiency of a Lucky Trade: Trade Stardust × 0.5, plus the Lucky 12/12/12 IV floor that removes the rerolling cost.
Mega and Primal forms are weighted as additional upside on top of the base form’s score, since the evolution amount comes from the same base Pokémon. Ultra Beasts are included as honorary Legendaries because they share the high Stardust power-up curve and Lucky-Trade compatibility.

The Top 10 — Best Legendaries to Lucky Trade

Zacian (Crowned Sword)
The single most versatile Lucky Trade target in 2026. Crowned Sword form is a top-tier Steel attacker, anchors Master League, and contributes meaningfully in Max Battle thanks to its Wall-equivalent kit. The exclusive move Behemoth Blade is locked behind a 1-bar Charged Move, so the second Charged Move slot still costs Stardust — making the Lucky Trade Stardust discount especially valuable here.

Zamazenta (Crowned Shield)
Crowned Shield matches Zacian’s Steel-type damage almost exactly while bringing one of the strongest defensive kits in the game. Its exclusive move Wall grants a free shield at the start of a Max Battle, which is uniquely valuable for the Tank role. If you’re heavier on Max Battle than Master League, Zamazenta may even outrank Zacian in your personal stack.
Groudon → Primal Groudon
The base Groudon is already the best non-Mega Ground attacker in the game, and Primal Groudon (when active) puts up the highest Ground DPS available. Primal weather sharing — Sunny boosts to Fire / Grass / Ground for the entire party — also amplifies your other Lucky Trade investments. Groudon is rarely available outside of Legendary Raid Hours, which is exactly when Lucky Friend trades are easiest to coordinate.
Rayquaza → Mega Rayquaza
Mega Rayquaza posts the highest single-attacker DPS in Pokémon GO across both Flying and Dragon, and its Mega aura grants a unique three-type damage boost (Dragon / Flying / Psychic) that no other Mega replicates. The base form is still a top-3 Dragon attacker on its own. Lucky-Trading a high-CP Rayquaza pays for itself instantly the next time you Mega Evolve.

White Kyurem
White Kyurem is the strongest Ice attacker in the game, and its exclusive move Cold Flare is one of the most efficient Charged Moves in any type. Ice is a top-3 most-used coverage type for raids (think Dragon, Flying, Ground, Grass weakness), so a Lucky-Traded White Kyurem pays dividends across many future raid bosses. Reshiram and Zekrom are absorbed as fusion fodder, so you’ll want as much candy as possible — Lucky candy reduction helps here.

Necrozma (Dawn Wings) & Dusk Mane
One trade, two specialists. Dawn Wings is the strongest dedicated Ghost attacker outside of Mega Gengar — and it has more bulk than Mega Gengar, which matters in long raids. Dusk Mane is among the top non-Shadow Steel attackers. Necrozma’s fusion mechanic lets a single Lucky Trade unlock both forms (using Lunala / Solgaleo as the second component).
Kyogre → Primal Kyogre
The Water-type counterpart to Groudon. Primal Kyogre is the highest-DPS Water attacker available, and its Primal weather amplifies Water / Electric / Bug damage for the entire raid party. The base form with Origin Pulse is already best-in-slot for many Fire / Ground bosses; Lucky Trade makes the second Charged Move and continued power-ups dramatically cheaper.
Mewtwo (with Mega X & Mega Y)
Mewtwo’s two Mega forms make it three Pokémon in one. Mega Mewtwo Y is the highest Psychic DPS in the game; Mega Mewtwo X is a top-tier Fighting attacker. The base form is also a viable Master League pick. Lucky-Trading a high-CP Mewtwo gives you the dust headroom to commit to the second Charged Move (Shadow Ball + Psystrike, or Focus Blast for Mega X).
Kartana
Kartana isn’t technically a Legendary — it’s an Ultra Beast — but Pokémon GO treats it like one for trade Stardust purposes, which means Lucky Trade is on the table. As a Grass / Steel attacker it’s the #1 non-Mega Grass DPS in the game and one of the few Pokémon in raids that can stand against multiple Mega-tier attackers without an Elite TM. If you raided Kartana during its event, the base candy investment is already locked in — Lucky Trade just makes the power-up free.
Xurkitree
Like Kartana, Xurkitree is an Ultra Beast that benefits from the Legendary Stardust curve. It’s the highest-DPS pure Electric attacker available and — crucially — its top moveset (Thunder Shock + Discharge) does not require an Elite TM. That makes it the cheapest end-to-end build of any pick on this list: candy from raids, no Elite TM, and a Lucky Trade that essentially zeroes out the Stardust cost.

Honorable Mentions
The following Legendaries didn’t quite make the Top 10 but are still strong Lucky Trade targets in specific situations:
| Pokémon | Type | Why it’s worth a Lucky Trade | |
|---|---|---|---|
.png) |
Dialga (Origin Forme) | Steel / Dragon |
Top non-Mega Dragon attacker after Rayquaza, and a top Steel pick. |
.png) |
Giratina (Origin Forme) | Ghost / Dragon |
Long-time Ghost main with strong durability and ML utility. |
 |
Lunala | Psychic / Ghost |
Required to fuse Necrozma into Dawn Wings — pair this with a Necrozma Lucky Trade for the Ghost role. |
 |
Solgaleo | Psychic / Steel |
Required to fuse Necrozma into Dusk Mane — pair this with a Necrozma Lucky Trade for the Steel role. |
 |
Ho-Oh |  Fire / Flying |
Niche Fire / Flying use cases, but consistently easy to find Lucky in the trade pool. |
How a Lucky Trade Pays for Itself — The Stardust Math
The standard cost to power a Legendary from level 30 to level 50 is roughly 1,500,000 Stardust without Lucky, or roughly 750,000 Stardust with Lucky. That’s a 750,000-dust saving per Pokémon — enough to fully unlock the second Charged Move on three more Legendaries. Two Lucky Trades on this list, in other words, let you build a fourth Legendary almost for free.
The Lucky 12/12/12 IV floor also removes the rerolling cost. With a non-Lucky Legendary, you may need to catch (or trade) several copies before landing a 14+ across all three IVs; with a Lucky, that risk vanishes.
