Commenting on the Pending list in the first post:
There are only 4 moves that I want to discuss in the Pending list, all others I pretty much don't care about whether they end up allowed or disallowed.
Disable - I think this move may have some niche uses, but is not as useful as it is on Gengar. Once behind a sub, not many pokemon run 2 moves that can effectively deal with Gengar, so once he disabled that one move, he's probably homefree to do as he pleases. On Tomohawk, even if you disable Thundurus's Thunder, Zapdos's Thunderbolt or Latios's Psycho Shock, they all have moves to do plenty of hurt on Tomohawk after it, regardless, while Tomohawk still can't do anything back. Thundurus may pack another Electric move in the form of Volt Change and this will hurt, even if it isn't Thunder. Zapdos can do Drill Peck, and Latios is a powerhouse regardless, so it can just continue to Draco Meteor Tomohawk into oblivion.
And that was just these 3 counters. Don't forget that BoltBeam is still a favourite move combo for a lot of pokemon and due to Tomohawks Flying type, disabling one means its likely you'll still get hit by the other. Disable surely harasses opponents, perhaps even forces switches (Thundurus Volt Switching out, because his main weapon is gone) but more likely than not, Disable will probably not give Tomohawk a safe ride for the remainder of that matchup. No reason to disallow, imo, so Allowed
Sleep Talk - I'm still of the opinion that if something isn't broken, don't disallow it. Disallowing should only be the hard list of moves that are deemed really detrimental to the concept or overpowering. I for one am all for keeping the Disallowed list only to the bare necessities, and let the movepool submitters decide what to slap on or not. They have limits of their own to worry about when making the movepool, and if the movepool they submitted is crap, or lacks reasoning, they aren't getting votes anyway.
With that said, I see absolutely no reason to Disallow Sleep Talk other than possible Prankster Rest/ST/Whirlwind/Roar sets. (Or Dragon Tail/Overhead Throw). This may be fixed by putting ST in a specific egg move group.
The reason why I want it allowed specifically, is that it works as a good sleep absorber with it. With Sleep Talk, it will even have one less problem to switch into Breloom/Gen 5 Mushroom pokemon/Smeargle with Spore. All of them can be hit SE either of Tomohawks STABs. Rest Sleep Talk also gives immunity against all other statuses that may cripple Tomohawk, most specifically Toxic, which puts a timer on Tomo's head. The being asleep part and the randomness of ST can be a bit offputting, but the longevity R/ST gives is great. I'd like to see this one allowed, but perhaps with the egg move restriction side note.
Switcheroo - Prankster Switcheroo looks to be absolutely hilarious, but may be Disallowed anyway, under the assumption that it will make Tomohawk able to deal with it's primary counters, by switching a lagging tail to them.
Still, I can see plenty of uses that come from an move like this, without being overpowered. As for gaining momentum with this move, I feel that's pretty obvious. If giving a bad item to your opponent's pokemon doesn't make him switch out, at the very least, it will put him likely in a situation where his pokemon is now less useful/useless.
I'm totally for Allowed on this one.
Wish - This fits Tomohawk perfectly, imo. We already have moves like Volt Switch/U-turn, Sub+Baton Pass, etc. It seems we'll be doing lots of pivoting. A pivot with a high HP stat (as Wish now looks at the HP stat from the one who uses it), and access to Wish and the ability to fire those Wishes off at +1 priority, I feel this gives some great tactical teamplay, prolonging both Tomo's life and that of his teammates, which in turn helps maintain momentum, as almost dead pokemon on your team are useless, but the ability to heal them up again can be very valuable.
Definitely Allowed, imo
Edit: @Jeffrey, those moves have already been Allowed, look at the first post, that Reach updated.
