Cresselia @ Leftovers
Trait: Levitate
EVs: 252 HP / 104 Spd / 152 Def
Bold Nature
- Hidden Power [Fire]
- Psychic
- Calm Mind
- Rest
After Tyranitar is dead, this thing can be deadly
Hydreigon pretty much walls the set too, actually, and even
Scrafty can be decent if it is the Bulk up variant. (Dragon Dance = Style Points)
All in all, Hydreigon can take a hit and hit back hard in return, unless you have, like, three or four boosts under you. This is to say, Hydreigon is less common.
That right there draws the point of how common
Latios is, and to a lesser extent
Latias, which do the same as Hydreigon but aren't Super Effective but take your hits. You
could get into a Calm Mind war, but you aren't very effective, and have to rely on rest. They have recover.
Heatran, oh my. Heatran gets the boost from Hidden Power Fire, takes Psychics, and Roars you out. It's probably the biggest of the walls to this set, simply because it can phaze you with ease.
Saying this, it's not really uncommon for a team to run Tyranitar and either Heatran, Latios, or both.
In the current Ou metagame, this set wouldn't work to it's fullest extent.
By the way: you
must comment on the set above you, according to the rules.
Edit:
Item focus sash
Anti hazard lead
movesets:
Spore
Spikes/ toxic spikes
Magic coat
Destiny bond
To be honest, I don't see this as being good. Maybe the Destiny Bond is pretty cool to see, but all else is meh. Spikes/Spore is sort of standard (Disregarding the SmashPash ultimate standard), and Magic Coat isn't reliable enough. What if your opponent knows what they are doing, and attacks/uses sub on Smeargle? Subleading Ninetales would certainly have no problems. Tyranitar can easily take you down to your sash, and let sandstorm kill you. Abomasnow will do the same, but can also sub up on you. If they see you have destiny bond, they can Leech Seed from there. That just leaves Politoed, who doesn't carry rocks anyway and will be left in as possible sleep fodder/will switch into a better person to take a sleep.
That's just weather leads; standard leads can also be problematic. A lot of leads use substitute, and Heatran dont afraid of Smeargle. What do you do against a team with Espeon? Risk Spore/Spikes? (I dunno how Destiny Bond works with the bouncing).
All in all, I always found sturdier Spike Setters/Make that guy sleep pokemon were better to set up, while Smeargle is merely there to baton pass, or just get in the way of the opposing team because it is frail and will only do one thing before death (SmashPass is still good, mind you).
Lastly: Evs are missing. Lolminorbutstill.
