Psychic/Water Move (surf or hydropump)
Psychic type are over powered in Gen 1. The best team is to find pokemon who can withstand the Psychic types. Starmie is very quick and therefore I start out with a minimize then substitute (possibly taking one attack), then I recover. Starmie can recover basicallly half of its Hp after the substitute takes the hit you will be fully recovered with a substitute andd hard to hit. You can either minimize 1-2 more times or just psychic them to death.
This is the same tactic as stamie except with out the waekness to electric type. Double team , Substitute, Recover , Psychic.....blah blah . Its a boring strategy but extremelyyyy effective. Alakazam is also super fast so you will almost always hit first.
This is my fun pokemon. Using a variant on the Substitute recover technique . I start with Hypnosis then substitute then... you guessed it, mega drain to get that HP back up! Exeggutor is the only grass pokemon in gen 1 not super effected by psychic type, making it perfect for an over powered gen 1 world.
I love charizard he is awesome. The second winning strategy is using toxic then any move similar to wrap like, I dont know, Fire Spin? once toxic is used that pokemon will die eventually. Toxic doubles up every turn so using moves similar to wrap lets toxic fully set in and start dealing great damage. I can use Motres for the fire version of this as well but not arcanine,,, never him.
Why use Mewtwo? Because DUH!,, he has the best stats in the game,,ANDDD he is psychic type. The only move that is super effective against him is pinmissle learned by beedrill and jolteon. lol it would be funny if either of them could last even one psychic attack by Mewtwo. Mewtwo is also one of the fastest in the game so you might consider teaching him doubleteam, but with his special as high as it is amnesia makes more sense. You could also use toxic instead of amnesia,, just for funsies, you could even use splash instead of amnesia with Mewtwo it wont honestly matter.
Oh whats that? You made it through the other Five Pokemon. Well unless your name is Gengar and thats very unlikely then you are probably in for a rough ride. Horndrill is for people like snorlax. Snaorlax`s one hit K.O. move Fissure only works if the one who uses it has a higher speed. I would think this is common knowledge but News Flash,, Snorlax is slow!!!! Tauros on the other hand is very fast and Horn Drill works on almost everyone. Nidoking is good with horn drill too, but psychic types tear him to shreds. Double team is good so you wont get hit as often. Hyper beam is just so if your opponent has 1 HP left and you could literally kill them with Tackle you still use Hyper Beam ,,because its just fun .
2 of these pokemon are intechangeable. This is an O.K. team I keep my actual more deadly team to myself if you message me I may give you the name of one of the other 2-4 pokemon I use instead. You may always need to change a few pokemon based on the opponent in any generation! No team is Perfect so experiment guys and have fun!!
