What Mega Evolution changes
Abomasnow, number 460 in the National Dex and a Sinnoh Pokémon,
holds Abomasite to become Mega Abomasnow,
taking its total from 494 to 594. The biggest single gain is 40 Attack, followed by 40 Sp. Atk. It also loses 30 Speed.
The typing does not change — it is Grass and Ice before and after — so the Mega is the same defensive problem as the base form, only bigger. The ability stays Snow Warning.
What gets through
As Grass and Ice, 7 of the eighteen attacking types get through for extra damage, and Fire lands for quadruple. It resists 4. The full board is above; the short version is that the
types listed under ×2 and ×4 are the ones worth planning around.
On the Regulation M-B ladder
Mega Abomasnow is played on 0.64% of teams in the Regulation M-B VGC
ladder, which puts it 90th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Blizzard at 98.6%.
The Champions module tiers it UU.
Those figures come from Smogon's published usage statistics rather than from anything measured
here, and they describe what the ladder plays, not what is strongest.
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 Abomasnow takes extra damage from.
- Kingambit — Iron Head (Steel, ×2), on 67.8% of its sets
- Incineroar — Flare Blitz (Fire, ×4), on 91.2% of its sets
- Garchomp — Rock Slide (Rock, ×2), on 75.9% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×4), on 99.2% of its sets
- Sneasler — Close Combat (Fighting, ×2), on 99.7% of its sets
- Archaludon — Flash Cannon (Steel, ×2), on 94.9% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Abomasnow is 57th by base
stat total. Its best stat is Attack at 132, which is 43rd
among Megas; its worst is Speed at 30, 87th.
No other Mega Evolution has the Grass and Ice typing, so this matchup board is unique to it.
The unevolved Abomasnow is itself on 0.03% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Abomasnow 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
132 points of
Attack actually change a
knockout.
