Winnifred
In order to sway this, you must have 2 or more Event cards currently in your Sway.
Trick-or-Treaters are both Events and Neighbors, so having 2 or more Trick-or-Treaters in your Sway will satisfy Winnifred’s Criteria.
Only count the cards in your Sway at the time that you declare that you are swaying Winnifred. If you later have fewer than 2 Event cards in your Sway, Winnifred remains in your Sway.
When scoring, this is worth 5 VP if it's in your Sway.
You may growl, “I smell children!” when swaying Winnifred, but only once per match or else it gets obnoxious.
