Quite a lot of damage to add to a Blade Dance in Act 1; instead of playing every Shiv in one turn you can play one per turn and deal 39 with them instead of 12. Phantom Blades is a little limited in terms of lategame scaling, but can help you survive long enough to find more exciting cards. It's fine to take this card and then move away from Shivs as a damage source as the run moves on.
for each Skill played this turn.
