Guide and Mentor - Perfectionist

[for] Only usable at the end of a successful action (after resolving the action). Untap this vampire.
[FOR] As above, but usable even if the action is blocked (play after combat, if any).

If the action is successful (all block attempts were unsuccessful), then the cost of the action is paid and the effects of the successful action take place. If the action is blocked, then any card played to take the action is burned (it is moved to the ash heap) and the blocking minion is tapped and enters combat with the acting minion (see Combat, sec. 6.4). The effects of the action do not take place when the action is blocked. Note that the action's cost, if any, is only paid if the action succeeds; the cost is not paid if the action is blocked. The costs of action modifiers and reaction cards are always paid when the cards are played, regardless of the success of the action.
