Well, when you think of Ditto, you think of what is arguably the best revenge killer in Pokemon. Thanks to Imposter, it copies the stats boosts of the Pokemon it transforms into, meaning that boosting may not be safe anymore. While it can't sweep a team outright, it is still very viable in Ubers. It can even copy into something like Forry or Ferro and set up entry hazards, meaning that having a Pokemon that has Stealth Rock on a team isn't even necessary anymore. Change its IVs to get a Hidden Power, can it handles that as well. While Ditto may not be broken enough to be banned in OU, can it still have an effect on the Ubers metagame. Is there a method on stopping Ditto? Will this blob effect how teams are now made? Discuss anything you want but remember to always enjoy the discussion! (so long as they're in the Uber rules)

This is Ditto's best, and only, set in the Uber metagame. With Imposter, Ditto automatically transforms into the opponent upon being sent into battle. Ditto has a bit of a four-moveslot syndrome, so choosing the correct move is imperative... Well, not really. If anything, Ditto has a one-moveslot syndrome. In fact, the only reason Ditto has a move is because without it, one would not be able to use Ditto. Still, Transform adds nothing to Ditto's utility, as Imposter accomplishes what Ditto would already do with Transform, though Transform does not copy stat boosts and wastes a turn.
Ditto should only be sent out against Pokemon that one wants to revenge kill, as that is Ditto's most effective role. This holds especially true against setup sweepers that have already acquired multiple boosts, as it simply makes Ditto more deadly. However, as always, one should never send Ditto out against an opponent that has a Substitute up, as Ditto cannot transform into a Pokemon behind a Substitute and will simply become dead weight.
Ditto's EVs are nearly useless in all situations except the very rare case where one's opponent sends Ditto out on the same turn that one's own Ditto is sent out. In this case, neither Ditto will transform, and a stall war will ensue. Thus, one wants to have the slower Ditto, as it will use Struggle after the opponent receives recoil damage, giving it an advantage. However, Ditto copies the stats of any other Pokemon that it transforms into, so the EVs serve no further purpose. Ditto does not, however, copy the opponent's IVs, so one should make sure that Ditto's IVs are set for the Hidden Power of choice. Using 30 Attack and 30 Defense IVs gives Ditto Hidden Power Ice, a good move for all-around coverage. 30 Atk, SpA, and Spe IVs can be used for Fire, as it hits Ferrothorn, Forry, and Skarm.
Ditto is a unique Pokemon, so it is only natural that it should be used differently than other Pokemon. Ditto should absolutely never be used as a lead or sent out to sponge a hit; these simply ruin its purpose. Instead, Ditto can be used to take on setup sweepers after they nab a KO, or simply revenge kill opposing threats. This puts Ditto users in a dilemma: what move should be used? As a general rule of thumb, Ditto should use a move that will allow it to stay in and do as much damage as possible. However, should Ditto be presented with an immediate threat that must be taken out, using the appropriate move and switching out will usually suffice.
Ditto is also useful for scouting opponents' movesets, as it copies every move. For example, sending Ditto out against Deoxys-S seems like a bad idea for the most part, but this actually allows you to learn whether or not Deoxys-S is an offensive variant or not. Similarly, one can scout setup sweepers in order to react appropriately and wall them, or to scout versatile Pokemon to learn how to stop them.
