Escavalier wins in 1v1 and 2v2 against Metagross, so that’s okay. It loses against Dragonite, Garchomp, Swampert, Charizard, Gyarados, Snorlax in the 1v1 (if it lands EQ), and Togekiss again. It does win against Mamoswine and Glaceon. The matchups are iffy and it doesn’t even max out above CP 3000. I’d rate this as unviable
Hippowdon is, without question, not viable. Only wins in the 1 v1 against Metagross, and 2v2 against Mamoswine. Loses against all the others.
Obstagoon does not even reach CP 2700. It could win against Snorlax and Mamoswine (if running Cross Chop, some run Gunk Shot for surprising Togekiss), but loses against everything else.
Gardevoir is okay. Fills pretty much the same role as Togekiss. I do think Flying is a better type to have than Psychic in this league though, as Gardevoir is weak to Snorlax’s Lick. I’d say Togekiss is better
Typhlosion is okay too. I mean, Blast Burn hits sooooo hard, it even hits well when resisted. It doesn’t weak against Swampert, Gyarados and Dragonite, but it puts up a good fight. Provided Blast Burn doesn’t get shielded up, though.
Lapras has great UL stats, but for ML… not so. Swampert used to be a decent matchup for Lapras; now it’s iffy. It probably still picks up wins against the dragons, but so do Mamoswine and Togekiss, while being more flexible.
Alolan Sandslash… no. Does not even reach CP 2500 and isn’t as defensively orientated as Lapras (to compare: Lapras has almost 5000 total stats at it’s max CP, and Alolan Sandslash has about 3800, which is pathetic for ML). It’s so weak, it almost loses to Togekiss in the 2v2. Actually, Togekiss even wins if it has a shield advantage. That’s not what a steel-type is for.
Haxorus is probably the best of these spice picks. And I think it’s hard to play with and to think of what moveset to use. Night Slash is mandatory to beat Metagross, Dragon Claw is mandatory to deal decent damage to dragons (though you still get shredded) and neutral matchups, Surf could be necessary to beat Mamoswine, and EQ is a great nuke to finish the game. Except against Dragonite, Gyarados and Togekiss (matchups you’d lose anyway).
