Proportional damage is unique and would set it apart from the others.

Now for the slightly longer reason.

Since your Wizard only targets those that have not been poisoned, he is great for attacking supports behind a tank. He'll be constantly eating away at everything's health until he dies. Naturally, it would be great if he had a way to finish off what he started since his damage is on the lowish side (he keeps switching targets remember, so the poison doesn't stack sometimes). Being able damage troops for 30% of their total health would be excellent. Of course, everything in his death/curse radius would get wrecked. But the ranged supports would not. Granted, everything with range equal to or below the Poison Wizards range would still be targeted by him. But at least they don't get deleted.

Long story short, obliterates the tank and the melee units in a push but ranged supports won't.

Also, I think the card would fit better a cursed guy who's really triggered about so he spreads it to other people. His spawn sound would a wheezy, maniacal laugh and when he dies, the curse curses everyone and they get wrecked.
