Shadow Alolan Ninetales

Shadow Alolan Ninetails is just barely good enough to be worth considering for a raid team, but it's not really good enough to utilize unless you're desperate for some Ice coverage. 

Best PvE Offensive Moveset

• Charm is the stronger fast move, and pairs with Dazzling Gleam to fulfill a Fairy-type role. 
• Powder Snow isn't far behind, and enables Shadow Alolan Ninetales to fulfill an Ice-type role. 
• Weather Ball Ice is the strongest and most consistent charge move available. 
• Blizzard and Ice Beam are a step down, though they're serviceable if TMs are lacking. 
• Feint Attack has no place on an offensive Shadow Alolan Ninetales. 
• Psyshock also has no place on an offensive Shadow Alolan Ninetales. 

Best PvE Defensive Moveset

• Charm has high power and good coverage, making it the ideal defensive move in general.
• Feint Attack is preferred over Powder Snow, due to higher base power and slightly better coverage. It can also hit Steel Types, which obliterate Shadow Alolan Ninetales, harder.
• Weather Ball Ice is the best charge move for defense, thanks to fast access as a 3-bar move. 
• Dazzling Gleam edges out Ice Beam, with better coverage and base power, but a later damage window. 
• Blizzard has too high of an energy cost for effective defense. 
• Psyshock can be used more frequently, but doesn't have as much power.
