The Poker variant is by far my favorite of the ones I've tried so far, plenty of cool choices. Is it supposed to end with only a few cards that can't match? I would expect it to auto fail or auto play the cards to see if you got a final set of points.
The Eldritch one confused me a bit, I too often ran into combinations that stalled the game out, with no combinations possible, or attack combinations that were insufficient. Would having the other attack slots open help loosen it up a bit?
Council of secrets overwhelmed me, but maybe I need really go over the rules some more. Leaving the instructions froze the game, weirdly.
Very cool idea, I like the different decks that add to the mood of each. Would love a right-click card view for planning, and to get used to the difference between a covered IV and a covered IX, and check out the art. I guess that might not work for all games.
