Regice needs Ice Punch > beam due to Higher Attack than SpA
What the heck ? Please do research before posting (
https://www.smogon.com/dp/pokemon/regice hint: look at the base stats. .__.), posting things you pull out your butt without researching, that isnt helping anyone in the slightest and you're guiding people down the wrong path. If i have to tell you again that is an infraction, ive had to do it one too many times to you and its beginning to get annoying. RESEARCH MOAR.
Also why are we all suggesting Physical Regice ? It frikking sucks, i thought the base 50 Att would kinda give that away. :/
Use Rest/Sleep Talk/Charge Beam, T-Bolt, S-Toss or T-Wave (you pick)/Ice Beam. 248 HP / 84 Def / 176 S.Def Plz on Regice.
Anyways, Regigigas is a tank and should be used as thus. Slow Start cripples it offensively.
Regigigas@Leftovers
252 HP / 252 Atk / 4 Def
Adamant Nature
- Substitute
- Thunderwave
- Headbutt
- Earthquake
This set is actually pretty annoying when played well. T-Wave and go for flinches to wait out Slow Start.
Registeel@Leftovers / Shed Shell
252 HP / 100 Att / 156 S.Def
Careful Nature
- Iron Head
- Earthquake
- Thunderwave / Explosion / Toxic
- Stealth Rock
Supporting tank. Shed Shell escapes duggy.
or
Registeel@Leftovers
252 HP / 6 Att / 252 S.Def
Careful Nature
- Curse
- Iron Head
- Rest
- Sleep Talk
Curse Talker. Pain to get rid of.
As for Regirock, the Curser is outclassed by Cradily and offensively its outclassed by Rhyperior.
https://www.smogon.com/dp/pokemon/regirock Depends on what you want it for really, if you're gonna use it use a set that utilizes its good s.def and better attacking stats and movepool to distinguish it from the aforementioned, the first set is a great example of that so id prolly use that.
Post evs next time because ya know those are kinda important. :/
And lastly
First Gen Toxic = Victory no matter what,
Toxic in first gen sucked ass, it went to normal poison (the non increasing damage kind aka bad) if you switched and took a turn to even damage you after you were inflicted with it.
