Blade of Ink is good enough value to make it into most decks without even considering its potential synergies. And it has a LOT of potential synergies; anything that cares about Weak, Shivs, or even Enchanted Attacks is excited to be paired with this card.
Think of this as +0, +2, +4, +6, etc. damage on each attack. It's not actually that much damage unless you can play 5 or more attacks. This goes hard with Finisher.
