Hello, I am here to talk about a strategy that was banned (in one form, at least) way back when in GSC, and it is threatening to make SM Ubers unplayable competitively: SleepTrapping.
As you likely know by now, Ubers uses similar clauses to other tiers, Sleep Clause being one of them. This clause has been essential for competitive play in almost any tier, because it allows for good players to make counterplay against sleep possible. A player can, with proper assessment of the in-match situation, make a judgment on how to play against a Pokémon with sleep move. It boils down to two choices: staying in with the current Pokémon used or switch. After a switch has been conducted, an additional switch into another Pokémon can be made in order to circumvent the passive effects of this status condition. This might sound incredibly simple, but it is important to understand that this clause is, in our eyes, not just a rule, but a philosophy on how to handle sleep.
SleepTrapping refers to the combination of [Sleep-Inducing Move] + [Permanent Trapping Move/Ability] + [Kill Move]. Essentially, you trap your opponent, induce sleep, and kill them by some means, usually with Perish Song or some attack. While SleepTrapping doesn't break the letter of the law of Sleep Clause, it does violate the spirit of it because you can't use sleep fodder. The clause never really comes into play with this strategy: you can just theoretically keep trapping and sleeping and the clause never truly activates. If you get caught in the SleepTrap, all you can do is hope you get lucky or die.
While SleepTrap never seemed to be a bother in Gens 3-5, it started creeping back up towards the end of Gen 6 and it came back with a vengeance at the start of Gen 7. Hypnosis Mega Gengar is becoming a hot topic among both community and moderators alike as a large issue to metagame growth, and with major tournaments such as SPL just around the corner, we felt it prudent to take action. Shadow Tag eliminates the foe's chance to switch out, and assuming the opponent attempts to send in a "check" to scare off Mega Gengar, the Mega Gengar user has ~84% chance to hit one of two Hypnosis. With STAB 130 BP Hex off base 170 SpA, all Mega Gengar has to do is hope the foe does not get a first-turn wake (66.6% chance) and they are usually dead. Even if the Mega Gengar only has an opportunity to use Hypnosis once, they still have roughly a 40% chance (.6 chance of hitting Hypnosis * .666 chance of not getting a first turn wake) of just ending whatever comes in with two Sleep-boosted shots of Hex.
What this means is that Hypnosis is effectively a legal OHKO move when used by Mega Gengar.
The change in Mega Evolution turn order mechanics has only served to make this strategy even stronger as Mega Gengar no longer needs to sacrifice a moveslot for Protect (which it needed to check certain Pokemon), allowing it to run Substitute to make the strategy safer or an additional coverage move to successfully SleepTrap a wider variety of opponents. This isn't even throwing in the potential for Perish Song.
Anyway, there are no plans to ban Mega Gengar itself. We already went through that song and dance once. Rather, we are proposing that we bring back the SleepTrap ban for SM Ubers as an extension of Sleep Clause. The proposed SleepTrap Clause would read as follows:
"A Pokemon cannot use a move that can inflict sleep status on the opponent if it has the ability Shadow Tag."
We do not believe such a ban would be unreasonable for Ubers to implement because of these reasons:
1) There is some precedent for banning SleepTrap in GSC. Granted, the specific ban is for SleepPerishTrap, and we are proposing a more general ban on SleepTrap. However, Perish Song isn't necessary to KO trapped targets in a timely fashion anymore, and the GSC ban did not factor in trapping abilities which defeats the main counterplay to SleepTrap in the old days (sending in a Sleep Talker).
2) The proposed ban is simply an extension of Sleep Clause. SleepTrap can be viewed as a loophole in our existing Sleep Clause: this proposal would serve to close that loophole.
We do believe, on the other hand, that banning SleepTrap is necessary so that the nascent metagame of SM Ubers can develop in earnest - especially given that SPL is right around the corner.
While this mostly pertains to Ubers, I am posting this here to give people a chance to voice any concerns, because I am well aware of how...controversial banning things in Ubers can be.
Thanks for reading!
