- Carrion Studies(your rank, 1 star). It is a 5 stars card. I know that are many bad deathrattle. The card is very good because it allows deathrattle hunter to have a turn 1 (which doesn't have it) and to discount the next card. So, you can play for example Bloated Pythonin turn 2. It is a 5 stars combo. It helps deathrattle hunter to be faster.
- Speaker Gidra(your rank, 3 stars). It is another 5 stars. Strong tempo card
- Cram Session(your rank, 1 star). It is a 3 or 4 stars card. It is a good card.
- Lab Partner(your rank, 3 stars). Easy 5 stars, it is 1 mana 1/3 with spell damage.
Carrion studies and devolving missiles are not 5 star cards. There are a lot of good minions you can devolve into and missiles is more random than the original devolve and Carrion studies would only be good in a deathrattle hunter and even in that you probably wouldn't run it.
