Mr. Rime@ Leftovers
Ability: Ice Body
Nature: Relaxed (+Def, -Spd)
EVs: 252 HP/ 252 Def/ 4 Sp.def
Blizzard/ Psychic/ Future Sight
Slack Off/ Protect/ Drain Punch
Foul Play/ Focus Blast/ Substitute
Strategy: Set up Hail first turn to damage all non ice types and have Ice Body + Leftovers to heal every turn and be hard to take off the battlefield.
- Hail sets up the hail weather condition and activates Ice Body
- Blizzard has 100 accuracy in hail and is powerful especially with STAB; Psychic gets STAB and has 90 power and 100 accuracy with a chance to lower the target's Sp.def and Future Sight attack 2 turns after it is used but in return for the wait it has a whopping 120 power and 100 accuracy and don't forget it gets STAB
- Slack Off can heal Mr. Rime if you're on low HP by 1/2 of max HP or you could choose Protect because it protects you (it's in the name) for 1 turn and could give you a turn to heal with Ice Body and Leftovers; Drain Punch is type coverage for steel, dark and rock types and heals half the damage you deal
- Foul Play is type coverage against Ghost types and could potentially deal a lot of damage if the opposing Pokemon has a high attack stat, meanwhile Focus Blast could be a good idea due to having 120 power and a chance to lower the Sp.def of the target and being coverage for rock, dark and steel types though it has 70 accuracy and is not recommended if you already choose Drain Punch, now Substitute make a decoy that could buy you enough time to heal up
Tips: This set is best when it's hailing so use Hail again when it stops hailing. Watch for dark types because they are immune to psychic moves. This moveset is a strong wall with high HP, defense and Sp.def. If I were you with the moveset , I would prefer special moves over physical ones but everything in this moveset is up to you.
I hope you like it! :)
