Jynx

From a Psychic-type attacker perspective, Jynx leaves much to be desired. The likes of Alakazam and Espeon aren’t burdened by the defensive liabilities of Ice-typing while also boasting higher Atk, to say nothing of monsters like Shadow Mewtwo which just plainly dwarf it by comparison When considering the classic Ice-types, Jynx stands above Cloyster and Lapras in terms of offensive capabilities, and was once the top DPS option for Ice Types. However, nowadays it's just a poor choice for the role.

Best PvE Offensive Moveset

• Frost Breath should be paired with Avalanche for one of the highest Ice-type DPS in the game.

• Ice Punch is a decent alternative should you want to preserve your legacy move.

• Confusion can be paired with Psyshock to fight Fighting and Poison-type Pokemon, but other Pokemon are better suited for the role.

• Focus Blast is inferior to other charge moves that Jynx can use. 

Best PvE Defensive Moveset

• Confusion is Jynx’s best move on defense, being one of the best fast moves for defense in the game.

• All of Jynx’s charge moves rate similarly on defense, with each having advantages over each other in terms of energy cost, dodgeability, and coverage.  

Confusion has a very nice stat line, providing above average damage with solid energy production. Frost Breath has inferior stats, but provides Ice-type coverage. 

Avalanche is a very strong move with great coverage and reasonable energy cost, making it a must have for dealing with many of the Pokemon that Jynx wants to counter. Psyshock is a cheap and relatively strong move that enjoys STAB, though Ice Punch's lower energy cost also makes it attractive despite the fact that it shares the same type as Avalanche.
