I played a few more battles today, and I'm happy to see that people are already beginning to realize how absolutely ridiculous Regice is. The other Ice-types that reside in the tier, such as Glaceon, Articuno, and Vanniluxe are interesting and need to be experimented with, but in all honesty it's really hard to consider them over Regice. Glaceon is more of a nuke with Choice Specs, but it lacks the pure bulk of Regice, while still maintaining a solid amount of offensive presence. Articuno has reliable recovery and Defog, but as a defensive wall or bulky attacker, my go to Ice-type would have to be Regice. Vanniluxe is just completely outclassed as a sweeper, because Regice can pull off a better Rock Polish set thanks to its better movepool and bulk. Here's the set:
Regice @ Life Orb
Ability: Clear Body
EVs: 32 HP / 252 SpA / 224 Spe
Modest Nature
- Rock Polish
- Ice Beam
- Focus Blast
- Thunderbolt
Max SpA and a Modest nature give it as much power as possible, while the EVs in HP give it a Life Orb number. Even after a Rock Polish, Regice doesn't even hit 400 Speed with a Modest nature, meaning that it's going to be outsped by faster Scarfers such as Electabuzz and Simisear, but other than that it outspeeds the entire unboosted metagame. Ice Beam is for obligatory STAB, and hits really hard coming off of a solid 100 SpA stat. Focus Blast lets it hit Gigalith and opposing Regice (very important) for super effective damage. Thunderbolt is there for Swanna, Relicanth, Tentacool, Simipour, Lapras, and anything else that resists Ice Beam. Although Sticky Web support is always nice to give it some sort of edge over offense before it sets up, Spikes support is better appreciated because it secures a lot more OHKOs that it might barely miss out on. Swanna is a good partner to this set because it can not only remove entry hazards that threaten to weaken Regice, but the two also have fantastic offensive and defensive synergy; Regice can set up on Pokemon that threaten Swanna, while Swanna beats Simisear and Fighting-types. This set will also need something to break through really bulky special walls that would wall this set otherwise, such as Grumpig, Clefairy, Metang, and even opposing Regice to an extent. CB Zweilous breaks through all the aftermentioned Pokemon with the exception of Clefairy with ease, while SD Guts Raticate with Crunch can pretty much level anything that could possibly keep Regice from sweeping.
Give this set a try! Regice is basically jesus in this metagame, so there's nothing to lose by using it.
