Moves:
Both Freeze-Dry and Ice Beam have the exact same freeze chance, so remove that line.
Mention that HP Ground also hits any fire types that may want to switch in Super Effectively, its not exclusively for Steel Types.
Also Frost Breath needs to be listed on this set, I honestly don't know how its gone without mention yet. At best it takes over Ice Beams slash, and at worst a mention in moves imo. Frost breath allows you to become an offensive check to CM Xatu regardless of how many boosts it has accumulated, granted you have to be weary switching in as +1 Psyshock OHKOs Cryogonal. This is something really niche Cryogonal has as a special attacker and it comes in handy given Cryo's great speed tier. Frost Breath can also be used to get the last bit of damage off on other CM Sweepers in the tier such as Musharna, Mesprit, Slurpuff, and Uxie.
252 SpA Never-Melt Ice Cryogonal Freeze-Dry vs. +1 252 HP / 0 SpD Xatu: 200-236 (59.8 - 70.6%) -- guaranteed 2HKO
252 SpA Cryogonal Frost Breath vs. 252 HP / 0 SpD Xatu on a critical hit: 320-378 (95.8 - 113.1%) -- 75% chance to OHKO
252 SpA Never-Melt Ice Cryogonal Frost Breath vs. 252 HP / 0 SpD Xatu on a critical hit: 384-452 (114.9 - 135.3%) -- guaranteed OHKO
+1 0 SpA Xatu Psyshock vs. 4 HP / 0 Def Cryogonal: 304-358 (107.8 - 126.9%) -- guaranteed OHKO
Usage Tips:
Mention that Cryogonal has a big niche over Kabutops in speed tier. If need be Cryogonal can spin on things such as Typhlosion, Zangoose, Sawk, and Electivire when Kabutops cannot. For teams that are especially weak to hazards I think Cryogonal is the better choice, party because of its ability to spin on a larger variety of threats. I also think you should state that while Kabutops can have an easier time dispatching spin blockers like Rotom and Mismagius, Cryogonal can also get past both of these if you choose to run knock off.
