Charizard
- Swords Dance
- Fire Blast
- Earthquake
- Hyper Beam / Body Slam
Charizard isnt TOO bad i guess. SD up and hit things hard basically. Fire Blast for STAB. Last slot is up to you, Hyper Beam is good as usual or you can body slam and fish for paralysis on things like Starmie.
Nidoqueen is generally outclassed by Rhydon, especially because this team is Snorlax/Normal attack weak, which is bad especially with Tauros being so common and good.
Rhydon
- Substitute
- Body Slam
- Rock Slide
- Earthquake
Sub up to scout counters then body slam to paralyze faster things and crush things with its insane attack. Helps lure in and weaken Starmie which will help Charizard.
Alakazam
- Psychic
- Thunderwave
- Recover
- Seismic Toss / Reflect
Standard Alakazam. Absolutely ridiculously good. Its like a mini Chansey with that great base 135 special. Thunderwave things and then drill things with Psychic. Recover lets you heal and the last slot is up to you. Seismic Toss is your best option vs Jynx, Exeggutor and the like or you can use Reflect to buff your defenses untill you switch out which makes Alakazam VERY hard to KO. S-Toss is usually better though as Psychic only has 16 PP.
Slowbro
- Amnesia
- Surf
- Thunderwave
- Rest
Classic TobyBro. Amnesia (arguably THE most broken move in RBY) to increase your special by +2 then you will be almost unstoppable offensively and defensively. Thunderwave to hit faster threats and scare things like Tauros. Surf for STAB and is your best move. Rest lets you heal and set up more Amnesia's.
Dont use Pikachu. Its pathetic to be quite honest and you wont win with it. I suggest Exeggutor as this team struggles with Golem and Rhydon.
Exeggutor
- Mega Drain
- Sleep Powder
- Psychic
- Explosion
Great lead. Has the possibility of taking out TWO pokemon when played well (one with Sleep Powder, another with Explosion). Mega Drain to nail those rock types and waters. Psychic for Gengar and is your most powerful move. Explosion to take out Chansey and the like.
Some other stuff you can abuse against your friend in RBY is; Chansey (over Charizard or Dragonite) who is one of the bulkiest Pokemon in the game with Softboiled and awesome special, Tauros who is the best clean up sweeper in the game and is really powerful. Mewtwo (the only thing that could replace Alakazam) who is simply THE most broken Pokemon to ever exist in any game period with Amnesia (if your friend doesnt play by standard rules, if he/she does however then Mewtwo is banned and for good reason lol).
