Flying

Whenever Voldaren Bloodcaster or another nontoken creature you control dies, create a Blood token. (It’s an artifact with “{1}, {T}, Discard a card, Sacrifice this artifact: Draw a card.”)

Whenever you create a Blood token, if you control five or more Blood tokens, transform Voldaren Bloodcaster.
