Dr. Visceric, Crooked Chemist

At the beginning of your upkeep, create a colorless artifact token named Mysterious Vial with "{t}, Sacrifice this artifact: Put a -1/-1 counter on target creature you control."
Each other creature you control with a -1/-1 counter on it is a Horror in addition to its other types and has flying, deathtouch, and lifelink.
"The effects will kick in very soon. It was nice knowing you."
