Vulkan, The Dragon

At the beginning of your end step, if you control no creatures with decayed, create a 2/2 black Astartes Warrior creature token with decayed. (It can't block.
When it attacks, sacrifice it at end of combat.)

"After death, after our duty is ended, we give
ourselves to these elements and in so doing
become a part of them. This is the nature
of the Circle of Fire."
—Primarch Vulkan
