What Mega Evolution changes

Magearna, number 801 in the National Dex and a Alola Pokémon, holds Magearnite to become Mega Magearna, taking its total from 600 to 700. The biggest single gain is 40 Sp. Atk, followed by 30 Attack. Nothing goes down — HP, Defense and Sp. Def stay exactly where they were.

The typing does not change — it is Steel and Fairy before and after — so the Mega is the same defensive problem as the base form, only bigger. The ability stays Soul-Heart.

What gets through

As Steel and Fairy, 2 of the eighteen attacking types get through for extra damage. It resists 9 and is outright immune to 2. The full board is above; the short version is that the types listed under ×2 and ×4 are the ones worth planning around.

Not legal in Regulation M-B

Mega Magearna cannot be used in the current Pokémon Champions regulation, so there is no ladder data for it and no legal set to report. Magearna is not legal either, so the whole line sits outside the format rather than just the Mega.

Regulation M-B closes on 9 September 2026, and legality is regenerated from the format data on every build rather than written by hand, so this page will change on its own if that changes.

What threatens it

Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is computed, not measured: these are the most-played Regulation M-B Pokémon carrying a damaging move of a type Mega Magearna takes extra damage from.

Where it sits among the Megas

Of the 91 Mega forms in the dex, Mega Magearna is 16th by base stat total. Its best stat is Sp. Atk at 170, which is 8th among Megas; its worst is HP at 80, 43rd. One other Mega shares the Steel and Fairy typing and therefore this exact matchup board: Mega Mawile.

Putting it on a team

A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Magearna would have wanted from an item, it does not get. Drop it into the team builder to see what the rest of the six then have to cover, or take it to the damage calculator to find out whether those 170 points of Special Attack actually change a knockout.
