Je me suis effectivement ptet emballe sur le double Obedience

Je reformule, histoire d'avoir un set-up correct.
Angela Preston declare une action. Matthias declare une block attempt.
Bima mel (Agent of Power, il vient d'etre mis en jeu) joue Siren's Lure.
Carna bloque Angela et joue Obedience.
Matthias peut-il encore jouer Gift of Sleep?
Name: Gift of Sleep
[HttB:C]
Cardtype: Action Modifier/Reaction
Discipline: Obeah/Obfuscate
[obf] [ACTION MODIFIER] +1 stealth.
[obe] [ACTION MODIFIER][REACTION] Only usable when this vampire is about to enter combat with an ally. Tap that ally and end the action. If this vampire is blocking, do not tap him or her.
[OBE] [ACTION MODIFIER] +1 stealth.
Name: Siren's Lure
[BL:R1, LoB:R]
Cardtype: Action Modifier
Discipline: Melpominee/Celerity
[cel] This vampire burns 2 blood to get +1 stealth.
[mel] Only usable by an untapped ready vampire other than the acting minion when a minion attempts to block. That minion cannot block this action. Tap this vampire and that minion. Once the action resolves, this vampire enters combat with that minion.
[MEL] As [mel] above, but do not tap this modifying vampire.
Name: Obedience
[Jyhad:U, VTES:U, Sabbat:U, SW:PV, CE:U, Third:U, HttB:PKia3]
Cardtype: Reaction
Discipline: Dominate
Only usable when this reacting vampire is about to enter combat with an acting younger vampire.
[dom] Untap the acting vampire, do not tap this reacting vampire, and end the current action (and combat). The acting vampire cannot attempt the same action this turn.
[DOM] As above, but do not untap the acting vampire.
[edit: il est probable que Bima ne soit plus "this vampire" quand on arrive a la fin de l'action, et donc le combat de siren's lure partirait dans l'espace]

Pour revenir a ta question:
A peut jouer Momentary Delay apres le combat avec le slave. A peut jouer Freak Drive (en sup' uniquement).
