just hit her multiple times per combat. If you throw a card you get one mana back, and it only cost one mana to draw, so just cycle your cards till you have what you need. If your int isn't too high, just use the 2 cost damage. Also add the healing spell you get in the intro, and just cycle for that every few turns
note to the devs, make drawing cost 2 mana and/or cost life, maybe even make each extra draw in a turn increase in cost, so that there is a down side and you cant just build your perfect hand each round. Also having a down side in the always avaible draw gives you design space for cards that draw. Otherwise, nice job on the card game revamp
