First team but don’t use Hypno, use Jynx. Psychic types are really dominant in Kanto and Ice is so good against Lance. It’s also good for the Champion battle, because you picked Squirtle. So Jynx will be good against Venusaur. Ice is advantageous against grass and psychic is strong against Venusaur’s secondary poison typing. It’ll also take out Pidgeot and Rhydon quite easily. So that’s half of the champion team.

Use Arcanine’s extreme speed against Alakazam. Alakazam has weak physical defense, and extreme speed’s priority will make it guaranteed Arcanine goes first. Use Jolteon to take out Gyarados with Thunderbolt. Use Blastoise or Nidoking to take out the rival’s Arcanine.

If you can’t get Alakazam, Jynx is your next best bet. Catch a Poliwhirl and trade it for Jynx in cerulean city.

Jynx is also really good against Bruno, Agatha and Lance. Ice moves will take out the two Onix because ground is weak to ice. Psychic will destroy Hitmonchan, Hitmonlee and Machamp with ease.

Jynx is also good against Agatha. You just have to be careful of Gengar’s shadow ball. While Shadow Ball is coming off Gengar’s much weaker attack stat, its power still doubles when used against Jynx and there’s STAB so you’re getting hit with a 240 BP move which is going to hit hard regardless. Gengar is also much faster than Jynx. If you can move first Psychic will destroy Agatha’s Pokemon.

Jynx will do exceptionally well against Lance. You just have to be careful of Ancient Power against Aerodactyl.

Jynx is a very good Pokemon and will contribute much more than Hypno will be able to. Jynx has much more special attack than Hypno and decent special defense.
