I just have to say that, compared to many weapons, this one is UP.
I know, I know, it has a great quanta/damage ratio, and it has momentum, blah blah blah.
But is being able to ignore shields is as good as having reusable CC (eagle's eye)?
or having epic PC (Pulverizer and Trident)?
or being able to stall your opponents deck (Eternity)?
Also, 7 damage is not much more than 5 or 4 when you look at the cost of that damage.
Besides, the main point of having momentum is doing lots of damage and having it be unstoppable.
Im not saying it needs a major overhaul to get some OP ability.
But it would be nice to at least have a few extra damages to get past their shield.
