[Submission] Spiking the vessel (Thanatosis)

Have thought about this over dinner:

Spiking the vessel
Thanatosis


Only usable when a minion is hunting. That hunt action fails (acting minion is still tapped). Place this card on the Vampire. The next time they would gain blood in any way, burn a blood and this card. Do not tap this reacting vampire.
Only usable when a Blood Doll or Vessel is used. This Vampire burns a blood and taps. Place this card and three counters on the Blood Doll or Vessel: the controller may burn a counter using a master phase action. When no counters are left, burn this card to be able to use the Blood Doll or Vessel again.

or alternative advanced:

Only usable when a minion is hunting. That hunt action fails (acting minion is still tapped). Place this card on the Vampire. The next time they would gain blood in any way, burn a blood and this card. Do not tap this reacting vampire.
Only usable when a Blood Doll or Vessel is used. This Vampire burns a blood and taps. Burn the Blood Doll or Vessel. The controller may burn X+1 pool to keep it, where X was the original pool cost.


The reasoning was that Samedi do a lot of wheeling-dealing (Little Mountain Cemetery and Off Kilter), so one from-the-shadows indirect method of weakening the enemy is to gum up blood/pool transfer.

I like this version:

Thanatosis

Only usable when a Blood Doll or Vessel is used by your predator or prey. This minion burns a blood and taps. The Blood Doll or Vessel is burned (including the blood being transferred).

the other ones have to much text that makes them clunky.
However there is one issue with them. Generally, it's bad design when you're mentioning name of the cards in card text (yes, villein and vessel are bad designs).
And why you're keeping restrictions to prey/predator in your propositions? It is not needed, decrease table interaction and increase lenght of card text. All of the things that should be avoided, if possible, when designing cards.
