>>51480630its a cool team, but in game it would be kind of hard to get. Exeggutor is a late game encounter that you need to baby sit to get the skills he needs. Zapdos is about the same point in the game. Snorlax is a little bit earlier and shellder you need the fishing rod you get at roughly the same time you meet snorlax
Gengar is really conflicting with some of the other mons. Generally he wants thunderbolt and maybe psychic, but Zapdos also wants thunder and Exeggutor wants psychic. Exeggutor also fills the roll of sleeper better with sleep powder so idk what Gengar's roll is on the team. Like he can tank normal moves, but so can snorelax, golem and cloyster.
Cloyster should be fine. It only needs one of aurora beam, ice beam or blizzard so TM issues aren't a big deal.
Golem just needs rockslide and maybe bodyslam but no one else needs bodyslam and there are different options for the 4th move.
Snorelax has multiple sets that I don't think conflict due to ice beam and blizzard both being good and bodyslam via level up
Basically my only issues are, what are you doing early game, what is Gengar's roll and Exeggutor is like Gyarados bad when it comes to the fact you need to get him exp to be viable, but you can get gyarados before Misty, where as Exeggcute needs to be level 48 for sleep powder and there isn't that much game left over at that point, unless you do something weird like purposely skip Erica and maybe surge and then over level every fight before Blane, because otherwise Blane's ace is level 47 and obviously Exeggcute is useless vs Blane so you just have him for dungeons, vermillion, victory road and the elite 4, which he is good at, its just again a lot of exp to dump into a mon that is only good for the end of the game and not a lot better in game than Venusaur and you could have used Gengar as your sleeper instead
