Blood and Water

 

For a long time, Blood and Water had one of the biggest draw effects in the game. 3 cards is a very large amount, and with only the added cost of an experiance (which shouldn't matter in the decks using it), it effectivly has a high card advantage of 2.

 

Obviously, Blood and Water is still strong. If stones become popular, it may eventually be replaced by Braving the Unknown, but for now, Blood and Water is strong in most alchemy decks, especially Izumi and Marcoh, and again, any deck that has a level 2 strong enough not to care about the level 3. It's powerful draw, there really isn't much else to say.

 

In sealed and speed draft, if you somehow miraculously pull a Blood and Water from a premier starter or something, then it would be very good, but it doesn't earn a rating do the the extreme odds against such an occurance.

 

Constructed: 4/5.
