Malleable Visage
Type: Action Modifier
Requires: Vicissitude
Cost: 1 blood
[vic] Only usable by a ready, untapped vampire. Usable when an ally
you control is blocked, before combat begins. The combat is canceled;
untap the acting minion and tap this modifying vampire. This vampire
enters combat with the blocking minion.
[VIC] As above, but usable when a vampire you control is blocked.
Yes (and the blocker loses the opportunity to diablerize, as in the Blood
Brother Ambush case).
