What are some cards that don't really get the recognition they deserve?
My favourite under-rated card right now is The Sting. I've seen people talk about how terrible it is, but it has won me far more games than I initially thought it would have. The first couple of games that I used it, I didn't quite understand the careful timing that it required, but once I figured out a strategy to make it work in my deck, it was a revelation.
What cards do you think deserve a second look?
