Diamond Boy 2 was added in Beta 6.6. Previous Versions can be found here.

This is a decent defensive card for 3G, with a decently high HP stat of 5 and the ability to reduce any damage you (the player) takes by 2.

This makes him a good card against opponents that like to quickly kill their opponents fast and leave the monsters alone. He counters Papyrus Statue's effect and is very effective against Pyrope and Loren.
