A) Why does he have to be the one to absorb sleep? You're already using good walls on the team that are better suited for that task. I don't think it's a good move for absorbing sleep when you have to go out of your way and make unsafe switchins in order to utilize said move, and then you're stuck with a CBer that you really have no control over. Using Sleep Talk without Rest puts your fate into the opponent's hands imo. Aside from that, 1 out of 4 total moves are unusable until he is put in this condition. That's 25% of your "resources" down the drain. What if you find him having to switch in on some other type of status like Para?
Well, its about the risk/reward factor, and also milotic isnt exactly a "dangerous" pokemon to switch in on either. If say, milotic or metagross gets slept, then he can get anihilated by any physical threat, and Gengar isnt in danger from pursuit. You also have to remember, he would only be using those 3 types of moves anyway, Focus Punch does the most on a switch, otherwise megahorn, Rock slide covers salamence/dos. Also, unpredictability makes your opponent uneasy, especially from a crazy Guts/CB attacker.
If he has to switch into another Status....?? He is immune to them, so he can. I dont understand that last sentance.....
B) When I send Hera out I'm generally not worried about Ghosts, Rock Slide will pretty much do it against a Gengar switchin, and noone would send in Dusclops on Hera unless they were sure it was EndRev with Salac I guess? And then they'd be switching in on a Substitute. Rock Slide and Megahorn will do the trick against both OU Ghosts, Gengar still doesn't like eating CB Megahorns despite the 4X resist, and Rock Slide should OHKO iirc.
The point is, it wont hurt them, at all. Gengar is a fairly common switch in too btw.
C) You say that prediction does not mean your team has a weakness, yet you use examples of good predictions in trying to explain the strengths of the team. Not all Milotics will just switch in and immediately Hypnosis, so your Hera will switch in on Surf, Ice Beam or probably something like Toxic (which while kind of cool at first, quickly becomes a pain in the ass), not a terribly safe task for somebody like CB Hera to attempt. Say Hypnosis does hit, then you're not even relying on prediction, experience and skill, but random chance :/ Even if Hypnosis misses, the Milotic user will know that you are holding a Hera (giving you the benefit of the doubt and assuming you hid Hera until now, which is pretty hard to do with a CBer), and that switchin will be that much harder to pull off next time.
Firstly, toxic is great to switch in, it does less damage then burns if you are hitting and running. Stab surfs dont hurt too much, but thats where prediction comes in, a milotic will clearly try to sleep something like snorlax or more obviously, gyarados(it cant stop it otherwise). Also, a free attack with a CBer is the point of it, to do as much as possible to whatever switches in.
Pocket I just don't know what you mean when you say Lax can switch in on Tauros. Even a very defensive spread will be taking minimum 2 STAB CB Returns before getting 1 Curse in, or 1 Return into a switchin to a counter. EV spreads just don't seem like they'd much of a difference here, though I admit I'm too lazy to do any damage calc or anything.
He didnt say it would switch in, it can just take a tauros 1v1.
I hadn't really noticed this before but it really looks like Zapdos can give you some problems. Lax won't like switching into repeated Tbolts, and pray that those aren't backed with Spikes. tbh I'd fear RestTalk Zapdos over Tauros if I were you.
Lax loves tanking tbolts and setting up curse, especially a weak restalkers tbolts.
