Counters don't make toons worthless overall. AoF is countered big time by GRE, yet you don't see people not using him because of that one counter.
However, he could be tweaked so that his take can't remove beneficial effects from toons who have immunity on the FIRST turn of battle. Then, afterwards, he could remove immunity. Let's face it, any toon that can AOE wipe out beneficial effects on the first turn is broken. Toons like MCR can only remove beneficials from ONE toon on the first turn, not the whole team (not to mention she's currently bugged and can't steal when a toon has immunity). VE renders first-turn defensive talismans useless, and that's not a feat any toon should be capable of doing.
