Ovormorph Egg

If an opponents creature attacks you, sacrifice this creature and create a 1/1 Facehugger creature token with "{1}{t}: Attach to target non-artifact creature an opponent controls. Attach only as a sorcery. As long
as Facehugger is attached to a creature it loses all other abilities and cannot attack or block. At the beginning of your upkeep you may pay {2}, if you
do, sacrifice Facehugger and create a 3/3 Xenomorph creature token with Acid Blood 1."
