Shard of focus offers permanent control to elements who do not have normal acces to it. I think this is a good thing.
Shard of focus regenerates a black hole wich is a counter to the meta defining speedbow. I think this is a good thing.
But where does it go wrong?
Is it because it can destroy multiple permanents? Pulvy does that too. This is not the problem.
Is it because it nerfs speedbows? Changing the meta is a good thing (it keeps us sharp). This is not the problem.
Is it because it does all these things at the same time?
Maybe...
Look, I have absolutely no problem with powerfull cards and I believe a card that both destroys permanents and nerfs speedbows at the same time can exist.
So, as far as I'am concerned, that is no real problmem.
The real problem about shard of focus is: IT IS ALMOST INDISTRUCTIBLE.
In fact, that by itself isn't the problem eather. Armagio is almost indistructible as well. So what's the difference? Let me tel you.
Shard of Focus is a creature with an epic ability that is even harder to destroy than a Pulvy.
That is , I Think, the problem. Only a lobo effect can stop it. But these effects are not so common in the meta. Other cc can't kill it, it can only slow it down by reversing or freezing it.
That's why tyhis card is OP and should be nerfed.
A good point to star is are his hitpoints. With low Hp this creature would be more balanced. At least we could counter it.
