Unholy Ritual
Play this card at the start of you turn. Choose one of your monster groups and draw Overlord cards equal to the number of figures from that group on the map. Choose and keep 2 cards and discard the rest. Each monster in that group performs 1 less action during this turn.
Played The Overlord Revealed recently, one of the monster groups was Kobolds. OL had 8 on the map before their portal closed and they were more or less out of the way down the red corridor. He had 2 Unholy Rituals in his hand and 2 other cards, which led to the following Unholy Combo. He was at the end of his deck, played UR, which brought about shuffling the deck of 11 cards. Looked at 8. Kept 2. Discarded 6. 5 left, played UR again on Kobolds. Drew 8 after shuffling the discard, grabbed another UR as one of his 2 choices. Player UR on Kobolds again, didn't get a UR that time, so the combo stopped. (He did it again the next 2 turns, similar to that, playing 3 UR on Kobolds each time).
Can you play UR twice (or more) on the same monster group, since they aren't being targeted?
Can you play it even when there are no more actions to lose for that group?
When drawing, you just keep perpetually shuffling so you can draw enough, right? I.e. 4 cards in draw stack, 4 in discard, just draw them all?
This seemed legitimate, we just simply weren't in a position to mess with Kobolds and help reduce his card draw. It was a sick strategy and quickly turned the quest around and kept all the heroes perpetually dead.
