Throwing Knife [Rogue Ability se103]

[Hednez]

Name: Hidden Knife
Casting Cost: 2
Effect: 3: Target ally receives 1 damage. If the ally was destroyed through Hidden Knife, draw a card.
Flavor Text: "Excuse me, but you've got a knife stuck in your back!"

A simple ally-finisher to draw a card. That's the whole idea about Hidden Knife; minor damage, but getting an extra card for killing.
So just to be clear: You attack someone and the attacked ally only has 1 HP left now. You cast the effect of Hidden Knife and draw a card. Also nice 1/1 killer (Sparks)!
I think its costs are fair, but if you want to lower them, do your magic!
