PvE Analysis

A Pokemon that completely lived up to the hype. Many players were afraid that Niantic would give Mamoswine a sub-optimal moveset pre-release, but this was definitely not the case! Mamoswine is the gold-standard for Ice Types and an outstanding Ground Type, sporting great power and decent availability. It's a staple for anything weak to Ice or Ground, and given how any big-name raid bosses have a double-weakness to Ice in particular, Mamoswine is always a great investment.
Best PvE Offensive Moveset
Powder Snow + AvalancheBest
Powder Snow + Avalanche is an ideal Ice Type moveset
Mud Slap + High Horsepower makes Mamo one of the absolute best Ground Types available.
Stone Edge is essentially strictly inferior to Avalanche, with low power and no STAB.
Ancient Power is purely cosmetic, a worse Rock move than Stone Edge. This is for collectors only.
Bulldoze is underwhelming.
Best PvE Defensive Moveset
Mud-Slap and AvalancheBest
Mud-Slap hits hard, and covers the Fire and Steel attackers.
Avalanche is a strong 90 power 2-bar move with early damage window.
High Horsepower is too slow as it is a 1-bar move.
Powder Snow does not deals much damage to attackers.
Stone Edge hits very early and may surprise Moltres, if it ever gets fired.
Bulldoze has a very late damage window and very easy to dodge.

PvP Analysis

Powder Snow + Avalanche and High Horsepower
Powder Snow is preferred for its high energy generation, which lets Mamoswine use its strong charge moves sooner. 
Avalanche is one of the most efficient charged moves in all of PvP, being both cheap and hard-hitting. High Horsepower is the second charged move of choice, giving it coverage for Steel- and Rock-type Pokemon. This is especially meaningful because Ice + Ground charged moves allow Mamoswine to hit virtually every Pokémon for at least neutral damage. Stone Edge can be used to eliminate certain Pokemon, such as Ho-Oh in the Master League, and is Mamoswine's strongest option against Water-type targets. Ancient Power is not recommended due to its very poor damage output. Bulldoze was formerly Mamoswine's second move of choice, but it is now strictly worse than High Horsepower.
Great League
Thanks to Mamoswine’s higher attack stat, it gets outperformed by Piloswine. Use that instead. Piloswine isn't even particularly good in the Great League; run Alolan Sandslash or Dewgong instead.
Ultra League
While Mamoswine has positive matchups against Giratina and Lugia, so does Piloswine, and so do better Ice-types such as Alolan Sandslash, which all have superior bulk. Once again, just use those instead.
Master League
While it does not possess the highest of stats, Mamoswine shines best in the Master League due to the abundance of Ice weak targets and the overall lack of Ice resistances. Thanks to Flying-, Ground-, and Dragon-types often running rampant, Mamoswine has many opportunities to leave a trail of destruction in its wake. Additional coverage from High Horsepower or Stone Edge further makes it trickier to handle; the former move can dent any Dusk Mane Necrozma that resist Avalanche, while the latter move swiftly removes Ho-Oh.
Despite its offensive prowess, Mamoswine does suffer from many flaws that can make it challenging to use. It is a fragile Pokemon with almost no resistances, and is cursed with weaknesses to common Fighting-, Fire-, Steel-, and Water-type attacks. It is a challenging Pokemon to teambuild with. Additionally, Hisuian Avalugg has cemented itself as a much more reliable Ice-type option. Although it lacks the ability to pressure Steel-type Pokemon, Hisuian Avalugg's much higher bulk and better Ho-Oh matchup makes it a generally much better option than Mamoswine.
