Someone mentioned this in the N / C moveset thread, and I was surprised to see that it was not on the analysis. I asked permission and wrote it this evening. Its a relativly simple set so I didn't feel that it needed too much explaining. I was unsure about the EVs, I decided in the end that emphasising HP and SpA was more important than Speed, as you want to come in on things that cant hurt it, Tentacruel for example and then hit things on the switch, but I'm prepared to be swayed. So any thoughts?

<p>Due to its considerable bulk, Regice has the ability to switch in regularly and dish out damage. Thunderbolt and Ice Beam are the core of this set and provide excellent coverage. Hidden Power Ground hits, for super effective damage, anything that resists the BoltBeam combo, mostly notably Magnezone. It also provides a handy OHKO on the ever popular Heatran. Explosion will put a large dent in Blissey, but won’t manage to KO unless it has taken 30% damage or so first. Focus Blast will do around a third to Blissey, but comes with the added bonus of OHKOing most Tyranitar. Even a 252 HP / 252 SpD Careful variant will take 80% on average. If running Focus Blast, you may wish to invest in 48 Speed EVs in order to outspeed no Speed Blissey. Blizzard will provide Regice with extra power, enough to give it at least a chance to OHKO Heracross and Gyarados with Stealth Rock up. This is only really recommended with use alongside Hail, as the accuracy is too low to be consistantly relied on.</p>
<p>The presence of Stealth Rock hinders this set, so the EVs are designed to compensate for that. With these EVs Regice has a lot more special bulk to allow it to switch into Special attacks better. This Regice can switch into a standard defensive Zapdos’ Thunderbolt and take a maximum of 18% damage, a Timid Life Orb Zapdos can only do a maximum of 28%. This allows Regice to switch in and fire off attacks more often than it could do otherwise. You can still severly damage Infernape and Lucario. If lucky you will OHKO them, however, they will die from their own Life Orb recoil next turn when not KOed, anyway. Celebi and Heatran are still always OHKOed by Ice Beam and Hidden Power Ground respectively, assuming Stealth ROck is on the field. Finally the HP stat hits 361 allowing you to switch into Stealth Rock one extra time if need be.</p>
