THe card states that "Action: Spend 2 resources to have a target unit gain 1 power until the end of the turn"
Can I keep pumping the same unit up by paying the 2 resources cost until I run out of resources? Or would I need 1+ Runesmiths to do this?
I can target any unit in any zone even my opponent correct?
So if I had 8 resources I could pump a unit up to 4 power plus his base power?
