Horrid Reality + Enhanced Coagulant

Hi, got a question regarding this combo, vampire plays Horrid Reality and gets an Enhanced Coagulant, strikes with it and hits, the weapon says that "it becomes a card with "Cards requiring a Discipline cost this vampire +1 blood. After this vampire successfully hunts, burn this card"", so,

Does it return to the deck? If it does, does the blood cost penalty still apply, or is it removed?

Because it feels imo, that the "it becomes..." was put there as a way to remind players that the opposite vampire is still afflicted by that card, but the weapon itself should be returned to the deck or sent to the ash pile if you play it as intended (no Horrid Reality involved).


Combat
Horrid Reality

Only usable before range is determined.
Chimerstry Equip this vampire with the first weapon you find in your library (working down from the top; shuffle afterward; if the requirements are not met, it is burned). This weapon does not contest any card in play. Do not pay the cost for this weapon. At the end of this combat, burn the weapon if it is still in play.
Superior Chimerstry As above, but shuffle the equipment into your library at the end of combat if it is still in play.

Equipment
Enhanced Coagulant

Weapon.
Strike: 3 unpreventable damage and put this card on the opposing vampire; it becomes a card with "Cards requiring a Discipline cost this vampire +1 blood. After this vampire successfully hunts, burn this card".
