I'm having a lot of trouble beating R'ashaht Rhiki. I've lucked out on getting two of her cards (complete accidents) but otherwise I lose way more than I win. My strat has been to use the King Elmer starter deck where you put cards in the corners but she never goes after my cards so I rarely win. If I put a card in the corner, she'll put one in another corner. XD I only have 54 cards so I don't have the unlimited 3 stars and even with my best cards, she kill kicks mah bootie.

So what's your strategy for defeating her?
