Specifically Tager. Any combo route ending with gadget finger => rc => Air grab (purple) => aerial Buster => gadget finger => rc => Air grab (purple) => aerial Buster.
Does around >7000 and uses heat. A high risk, high reward, very gimmicky combo (?). If the air grab fails, you can aerial buster them if they don't do anything and just float there.
And when I mean it's legit, I mean if it is fair game, from a moral point of view.
