Corporate Downsizing
This achievement is currently "Win 2 different campaign scenarios on expert difficulty with all players in your team using decks containing no more than 5 total cards."
This is a lot of fun and I want more.
I suggest we turn it into a progressive achievement, 2/4/6/8/10
Rewards:
2: Gold (Portrait)
4: Platinum (Portrait)
6: Diamonds (Portrait)
8: Promo Necroblaster or Magma Hurler
10: Frugal Tactician (Title)
Doesn't really matter what the rewards are, though last one should be a title.
Promo Necroblaster or Magma Hurler because they're both strong choices when doing the achievement, especially if you're doing Cheapskate at the same time.
