Welcome to a fairly fun part of your team. The description of this pokemon is right in the name. He takes revenge for your fallen pokemon with either incredible speeds or priority level attacks to take out the low health pokemon that was left behind. It can even sweep later in the battle. So without further a due, let's get started.
Item: Life Orb
EV's: 252 Att/ 252 Spe/ 6 Hp
Moveset: Bullet Punch
This is something that for some reason has been growing less popular and I don't understand why. It is and always will be a great revenge killer. With his Technician ability, life orb, and STAB (Which means it deals 1.5X more damage since the move's type is the same as the pokemon) Bullet punch will have a eally nice power to it, and it has priority on it, making it a first hit no matter what the speed of the enemy pokemon. Now we can add the power of Technician and life orb to pursuit, and if you can catch a pokemon being recalled, it will deal twice as much damage, and this all eqauls out to a lot of unconcious pokemon. Having Super Power and X-scisor are simply for the late battle sweeping I mentioned earlier.

Item: Choice Scarf
Nature: Don't bother
EV's: Don't bother
Moveset: There's only one, and you neve gonna use it.
Hello there non-believers. For those of you out their who doubt the awesome power of this little ball of attempted Mew slime. Thanks to his recently made ability, Trickster, he will instantly transform into whateve pokemon is out at the time, not only that, but he will gain all curent stats of that pokemon and all moves. The reason this is so good is because you will be gauranteed faster thanks to choice scarf, and you can use the sweeper moves that your opponent has to finish off the enemy. You can also take this little bundle of joy and up it up as a lead, taking advantage of that speed and copy ability to use their lead's set up moves. This is why I honestly believe he is the 2nd best revenge killer in the game, due to his vesatility.
A revenge killer is a great addition to any team, due to the ability to finish off threats to your team. Some good moves to have on a revenge killer are Mach Punch, Ice Shard, ExtremeSpeed, and Sucker Punch. Some other good revenge killers are anyoe with incredibly high speed or one of these moves. This one, unlike others, all depends on personal preference.
