Ah its been years since I've played the RBY Games. Well time to take a trip down memory lane with a Rate My Team.
Gengar
~ Hypnosis
~ Explosion
~ Thunderbolt
~ Mega Drain
My favorite Poke'mon ever. Make the first Pokemon G.T.S( GO 2 SLEEP) with Hypnosis, Thunderbolt rules, Mega Drain for Rhydon and Golem, and Explosion when Gengar is done.
Rhydon
~ Earthquake
~ Rock Slide
~ Substitute
~ Body Slam
Body Slam to paralyize some Poke'mon, Earthquake and Rock Slide are killer Stab moves, and Substitute to scout.
Chansey
~ Softboiled
~ Ice Beam
~ Thunderbolt
~ Thunder Wave
Chansey! who ever thought it would get an Evoultion later on to make it even better. Chansey takes Special Hits like nothing! Softboiled to instant recover, BoltBeam duh!, and Thunder Wave.
Persian
~ Slash
~ Bubblebeam
~ Hyper Beam
~ Thunderbolt
Ah kitty kats. Slash and Hyper Beam is take advantage of Persian's high Critical Hit Rate, Bubblebeam is to take out Rhydon and Golem, and Thunderbolt is to take on everything else.
Slowbro
~ Amnesia
~ Surf
~ Thunder Wave
~ Rest
TobyBro. Thunder Wave as much as the opponent's team as possible(excluding Chansey.), Amnesia to raise Slowbro's Special Stat, and Rest to heal.
Zapdos
~ Thunderbolt
~ Drll Peck
~ Thunder Wave
~ Mimic
Zapdos is only good when Rhydon / Golem have been removed after that Zappy is one helluva late game sweeper. Thunderbolt and Drill Peck for Stab, Thunder Wave to paralyize Poke'mon, and Mimic because Zapdos movepool is limited.
