>>31666834> Do you think it is important to have a Rock/Ground on the team?That largely depends on many psychic pokemon + chansey you're running.
The early game to mid game is all about baiting para, getting a freeze if you can, and wearing your opponent down. The problem is is that a pokemon like snorlax requires no setup to use whatever so ever, so if your early game goes horribly wrong ( you get frozen or untimely crits push your shit in) you're still good to go.
But if you're running a rock and you get totally destroyed in early game, then you basically have to give it up for free and rely on your end game sweeper to pull a hailmary. The ONLY reason to use rhydon over golem is to challenge paralyzed starmies. Since starmie isn't as common and your opponent is unlikely retarded enough to get it para'ed, I see almost no reason to use rhydon. At least with golem if your early game gets fucked, you can explode. If you get caught with rhydon when your support failed, you're totally fucked.
The more psychics + chansey you have the greater of margin of error you have for early game, so rocks become more attractive. If you have 1, I'd say no. 2 maybe. 3 or 4 I'd say go for it unless you have other plans.
It also depends on the current stage of the meta because the presence of zapdos is cyclical. You don't NEED a rock to deal with that pokemon, but if you do you can basically get a one mon advantage on the spot if you don't lose your rock since they can never use zapdos and you can force a couple predictable plays.
So the importance of it depends on your team and the current meta. It's good but not required.
