Biotransference
Enchantment
Creatures you control are artifacts in addition to their other types. The same is true for creature spells you control and creature cards you own that aren't on the battlefield.
Whenever you cast an artifact spell, you lose 1 life and create a 2/2 black Necron Warrior artifact creature token.

Replacement effects that modify artifacts as they enter the battlefield will apply after you apply Biotransference's effect. For example, if you control a Biotransference and there is an effect that says artifacts enter the battlefield tapped, creatures you control will enter the battlefield tapped.
