To be an 'tank' killer, then one or both of these two options must exist in order for it to qualify being a tank killer.

1) The champion's main damage output must be able to ignores/or bypass a lot of the enemy's resistance 2) The champion's damage gets better the tankier the champion becomes (either it be more health, armor, or MR)

Can a champion actually exist that main role is to just kill the tank and still be balanced. Well yeah a champion like that could exist and actually be totally viable. It may be the norm to say that you should never focus on killing the tank, but the reason why that is the consensuses is because it generally takes too long to kill those tanks. But if you could blow them up quickly like any other champion, then this is a huge boost to a team because now your main damage dealer is free to be on the aggressive without fear of getting jumped. It's the tank's job to prevent the enemies backline from attacking your backline, but if that tank can't even survive, then that's a whole boost.

But after saying that, a few things that comes to mind that must also exist if that's their main role while trying to be balance.

1) This champion cannot scale well into the late game (in terms of damage & tankiness) since being a tank killer is basically means that champion has no possible counter-build. 2) This champion cannot also be innately tanky nor can it have enough flat damage and utility where it can be a true threat just by building pure tank (or 1 offensive item then pure tank).

Pretty sure there will need to be a lot of balance checks as well such as mechanics, but that's all I can think of at this very moment.
