My point being is that you pretty much HAVE to sacrifice something to get Ditto in safely against a +3/+3 monster, which yes, is how a revenge killer works. Yes, Ditto most likely will revenge kill, but Ditto can't really set up again if it's forced out without sacrificing another Pokemon. Scarf Ditto is forced to use one move that you know in advance with 5 PP. It'll destroy what it's revenge killing and maybe will sweep if you aren't careful, but it IS beatable.I hate to say it, because its been said like 20 times. But Vakama. Your 3rd point... REVENGE KILLER. He comes in AFTER a pokemon dies. WHY THE HELL would you send him in front of an attack? Let him come in after the death of one of your own.
This literally needs to be written in capital bolded letters and bright colors on the first post because everyone keeps saying that same issue. "lol send ditto in while my gyara is using dd, now your plan is flawed." Yeah. If I am an idiot and don't know how to revenge kill correctly.
Ditto will be a fabulous revenge killer and will be my revenge killer of choice, but I don't think it's broken enough to warrant a ban.
