What sort of OU teams best use Omastar? My understanding is that its something to pressure Lax with but Im uncertain the tradeoffs of running her and how that affects the rest of the team.
Based on ladder play, it would work on a team with freed

(Non-counter All out Attacking). You use it like

, you keep it safe and use it to scare away Lax with the threat of Hydro Pump. At that point, you need to figure out how to deal with the switch-in, which is usually

. You play the team much differently than you would with Reflect Lax. You want to use your own Snorlax to handle the non-Normals, rather than having your Normals tackle the opponent's Normals.
The dex entry suggests you use Body Slam. It is an option, but it's fourth moveslot is pretty mediocre. I personally believe Toxic star paired with Leech Seed

is an option. The idea is to prevent you from auto losing to Amnesia sets and nothing else (aside from being amusing). You want to get the toxic counter increased, then you stall until the Amnesia user sleeps, then you seed them. This heals an enormous amount of HP. (Only attempt the toxic seed glitch against Amnesia sets). Toxic also helps against

if it's the final mon. If you are wondering "well couldn't they just swith out their Amnesia set into

Ya, but then

did its job at with forcing out the Amnesia set. Gen 1 is full of situations where you must make tricky plays, so I don't think Toxic is a wasted moveslot.

is almost a given, in my eyes as a teammate, b/c of

and Ground
Anyways, I don't really play tournaments, but from ladder play this team seems decent:





I haven't used it, but have seen something like this on Ladder:






Sauce (see Sevi's post):

Notice the Sevi uses Submission, though I'm surprised that it doesn't use Rest. They also don't run Lax which surprises me. Rhydon is likely a replacement due to the threat of
Perhaps it looks like it's a trash mon, due to the limited amount of teams it can be on (maybe). I think it also depends on what plays people are more likely to make. Up to you, if you want to try it out, but be smart about your plays.

Anyways, I have a question:
How do you go about paralyzing an opponent's entire team?
I want to experiment with

as an end game mon to see how it compares to a mid game mon (which is how I use it). I also want to know how to properly use

, b/c I question what it has over

.
