Cryogonal's evolution

Cryohomun (Cryogonal + homonculus)

HP: 80 (301 - 364)
Atk: 50 (136 - 199)
Def: 40 (116 - 179)
SpA: 100 (236 - 299)
SpD: 140 (316 - 379)
Spe: 130 (296 - 359)

From these stats, we can see the potential of Cryohomun. It excels at walling special threats, but fails to wall physical threats. That said, Cryohomun is also fast for a special wall, and that high Speed combined with decent Special Attack can allow it to go onto an offensive role.

Types: Ice / Steel

This typing is considerably bad, yet good at the same time. Cryohomun has plenty of resistances to abuse thanks to that Steel-type, while its weaknesses are easy to exploit-4x weaknesses to Fire and Fighting and a Ground weakness will make Cryohomun a lot harder to use. That said, with 9 resistances and an immunity to Toxic, expect Cryohomun to wall certain threats.

Ability: Levitate

Levitate, Levitate, Levitate. When you thought an immunity to the Ground-type attacks that Cryohomun is weak against was a godsend, wait until you hear this: immunity to Spikes! That gives Cryohomun a great role in Rapid Spinning-it only takes 12.5% from Stealth Rock. High Special Attack and Ice Beam allow it to defeat Ghost-type spinblockers, and access to Recover allows it to maintain longevity. Levitate also gives Cryohomun more switch-in opportunities.

Important Moves:

Level 13 - Rapid Spin
Level 33 - Ice Beam
Level 49 - Recover
TM06 - Toxic
TM10 - Hidden Power
TM24 - Thunderbolt
TM52 - Focus Blast
HM03 - Surf

From Cryogonal, Cryohomun gained three important moves. Focus Blast, Thunderbolt, and Surf complete the coverage on the Life Orb set. Ice Beam, Thunderbolt, and Surf have great coverage together, as demonstrated by Starmie. Focus Blast can be used to harm Normal- and Steel-types.

Interesting Moves:

Level 21 - Haze
Level 37 - Light Screen
Level 37 - Reflect
Level 45 - Confuse Ray
TM64 - Explosion
TM90 - Substitute

These moves have a niche for specific sets. Light Screen and Reflect can be used to patch up its team's defenses, Confuse Ray can be used to damage physical sweepers and Haze wipes boosts clean. Explosion has its use in bringing down a weakened opponent, but kills Cryohomun in the process. Substitute can be used on any set to block harmful moves like Leech Seed and Thunder Wave.

Let's explore two potential sets for Cryohomun:

[SET]
name: Rapid Spin
move 1: Rapid Spin
move 2: Recover
move 3: Ice Beam
move 4: Toxic / Hidden Power Fire
item: Leftovers
ability: Levitate
nature: Calm
evs: 252 HP / 4 Def / 252 SpD

Rapid Spinning is an important role on teams. It stops phazers from wearing down your team, sweepers from obtaining OHKOes on your important Pokemon, and much more. Thankfully, Cryohomun's neutrality to Stealth Rock, Levitate ability, access to Recover, and ability to wall special attackers, combines to form a team player. Rapid Spin and Recover combine to form a combination that Cryohomun can rinse and repeat, removing deadly entry hazards and getting ready to remove more. Ice Beam is used to damage Ghost-types attempting to block your spin. Toxic is a great way to wear down Jellicent, who walls Cryohomun otherwise. Hidden Power Fire can be used to stop Forretress and Ferrothorn, who otherwise have a field day with Cryohomun.

[SET]
name: Life Orb
move 1: Ice Beam
move 2: Thunderbolt
move 3: Surf
move 4: Recover / Focus Blast
item: Life Orb
ability: Levitate
nature: Timid
evs: 4 HP / 252 SpA / 252 Spe

This isn't your supporting Cryohomun; it can jump into the offense and begin to tear apart holes in the foe's team. The key to this secret is great SpA and excellent Speed, three important coverage moves, a great ability in Levitate to grant more switch-in opportunities and take no damage from Spikes, an immunity to Toxic that cripples other sweepers, and access to Recover. STAB Ice Beam destroys any Pokemon that doesn't resist it. Thunderbolt hurts Water-type Pokemon and Skarmory. Surf crushes Rock-, Ground-, and Fire-type Pokemon for super effective damage. Recover heals up Cryohomun nicely while Focus Blast pounds Ferrothorn and Tyranitar. Hidden Power Fire could be used for Scizor and Ferrothorn.
