Possible team? I really have no idea...

[Mr.Sandman]

Please note that this team was made relatively quickly and has not actually had much practice as of yet. It is just a work in progress that I would like some feedback on :)

1. Infernape @ Focus Sash

Jolly - Blaze
6 HP/252 Atk/252 Spe
~ Fake Out
~ Stealth Rock
~ Roar
~ U-turn

My take on the ever-popular Lead-Ape. Acts as a scouter for my team with U-turn and Roar, and is fast enough to get up stealth rock, survive a hit, and still be able to u-turn out or roar.

2. Miltank @ Leftovers

Impish - Thick Fat
252 HP/212 Def/40 Spe
~ Milk Drink
~ Heal Bell
~ Counter
~ Body Slam

This guy might be walled pretty easily by ghosts, but he packs quite a punch. Heal bell is phenominal for helping out my team, and Counter works extremely well with his high defenses and HP.

3. Flygon @ Choice Scarf

Mild - Levitate
152 Atk/220 SpAtk/136 Spe
~ Outrage
~ Earth Power
~ Draco Meteor
~ Fire Blast

Again, my attempt to be creative with a Scarfed Flygon. I tried to go for more of a special based Flygon, with Outrage as a backup in case I use one too many Draco Meteors. Works extremely well as my late game sweeper.

4. Lucario @ Choice Specs

Modest - Inner Focus
6 HP/252 SpAtk/252 Spe
~ Hidden Power Ice
~ Vaccuum Wave
~ Shadow Ball
~ Close Combat

IMO, SD Luke has become too popular for its own good, and there are too few Specs Luke's anymore. This guy can demolish pretty much anything that expects the normal SD Luke. I know what you're thinking, about close combat over Aura Sphere, but to be honest, it guarantees an easier 2HKO on Bliss than Aura Sphere, even with the -Atk Nature.

5. Dusknoir @ Leftovers

Careful - Pressure
252 HP/200 Def/56 SpDef
~ Will-O-Wisp
~ Pain Split
~ Shadow Sneak
~ Fire Punch/Thunder Punch

An evenly-oriented Dusknoir, designed to take hits from both Special and Physical attackers with ease. Fairly standard moveset apart from the careful nature.

6. Donphan @ Leftovers

Impish - Sturdy
252 HP/ 58 Atk/200 Def
~ Rapid Spin
~ Earthquake
~ Ice Shard
~ Stone Edge

My rapid spinner and strongest physical attacker. He serves as surprise sweeper at times when the opponent is led to believe that it is only to be used as a utility/defensive wall.

I can already tell that this team is lacking a bit on the physical side, so please take that into effect when rating. Also, I am most hesitant about Donphan on my team, so if you have anything that you think could replace it (or anything else really) feel free to say so. Any suggestions you have would be greatly appreciated. Just try not to flame it too much, it was just a kinda random team that I put together extremely quickly ;)​

Since Spikes and Toxic Spikes are rare, and nothing on your team is weak to Stealth Rock, you may be able to live without a spinner, which would allow you to drop Donphan for another Physical Attacker.

Whereas I like the idea of the mixed Flygon, his SpAttack is just too low to being significant damage with anything but Draco Meteor to a lot of common Pokemon, barring Heatran.

I've not tested Roar out on a Focus Sash lead, but I don't think it'd be doing a lot of good. Take, if you will, these scenarios.
Scenario 1:
You send out Infernape.
Opponent sends out Attacking Lead.
You use Roar.
Opponent uses powerful attack that would normally OHKO. You hang on using Focus Sash.
Opponent's Pokemon is dragged out.
If their Pokemon is slow, you use Stealth Rock / U-turn. Infernape either dies, or becomes a liability for late game.
If their Pokemon is fast, you use Fake Out, but die the next turn anyway, unless you switch, in which case, Infernape again becomes a liability.

Scenario 2:
Opponent sends out Tyranitar.
You use Fake Out.
Sandstorm nullifies Focus Sash. Tyranitar uses Earthquake. You:
Die due to using Roar and its negative priority.
Use U-Turn and switch out, but become much less useful for late game due to being a scout Pokemon.
Use use Stealth Rock and die as a Suicide Lead

The second is situation, but it could work with Hippowdon, and on occasion, Abomasnow too. I'd suggest dropping Roar. The negative priority just doesn't work well for weaker Pokemon. Perhaps you could replace it with Endeavor, or a strong attacking move, like Overheat?

If you add another Physical attacker, give Lucario Aura Sphere. Even for Blissey (who is 2HKOed if she doesn't invest in SpDef), Aura Sphere is still more preferable since Lucario typically won't stay in against her, and if they switch into you, you'll likely be locked into something other than Aura Sphere.

I've not tested Roar out on a Focus Sash lead, but I don't think it'd be doing a lot of good. Take, if you will, these scenarios.

I agree with most of your suggestions, but I think that in both of these cases, you assume that the opponent will outspeed Ape, which, considering that its speed should top out at 346, would only be out sped by the fastest leads, namely Weavile, Crobat, Jolteon, Gengar, Ninjask or any Scarf Lead. In any other case, it would be able to either set up SR and then Roar, Fake Out the opponent, or U-turn to a sweeper.

In this case, Roar is only used for scouting purposes. Nonetheless, your suggested moves would both work on the set, I may try both out.
