I really like these cards with the negative abilities because you can get a powerful monster by only spending a little bit of mana. If you play your cards right and put them in a position where you can minimize their weaknesses, they can be a great value driver. I like putting Water Diviner in the first position as a sacrificial damage sink kind of like how I used to use Kelp Initiate back in the day.
