Mr. Rime

Mr. Rime was initially released through a special ticketed event, making it originally somewhat limited in terms of accessibility. With only 212 ATK, Mr. Rime falls behind other Pokemon in terms of stats, making it a downgrade when compared to other existing options. A total of 6 weaknesses and only 2 resistances makes it a poor choice for gym defense. 

Best PvE Offensive Moveset

• Confusion is stronger than Zen Headbutt, making it the stronger option to pair with Psychic.
• Ice Shard pairs with Triple Axel for maximum Ice Type damage output for Mr.Rime.
• Psybeam, Ice Punch, and Icy Wind are sub-optimal.

Best PvE Defensive Moveset

• Confusion is the best fast move for defense due to its high base power and synergy with Mr.Rime's best Charged Move option.
• Zen Headbutt and Ice Shard fall behind due to their lesser damage potential.
• Triple Axel is the stand-out Charged Move, as it comes out frequently, is hard to dodge, and has solid power.
• Ice Punch, Icy Wind, Psychic, and Psybeam are sub-par options.

Confusion sports superior damage output, while Ice Shard offers faster energy gains. Either can be chosen depending on coverage preferred. 

Icy Wind is valued for its debuff mechanic, though it's not the most powerful or efficient charged move. Triple Axel is virtually identical to Icy Wind, but it buffs Mr. Rime's Attack instead of debuffing the opponent's Attack. Ice Punch costs the least amount of energy and can be used to pressure shields sooner, while Psychic demands more energy but offers Psychic-type coverage. Psybeam is a poor move for PvP.
