My 9-year-old son and I love playing Sentinels, including the Infernal Relics expansion (though we don't do Gloomweaver or Tombs of Anubis). We would like to take on a tough villain like The Matriarch but were wondering whether any of her cards are not appropriate--either in image or text--for a 9-year-old. Any ideas?
EDIT: There is an example of the artwork for a particular villain called Spite in that thread, one who I would view as the most age-inappropriate villain... and even then I'm not sure it's scary if given proper context to a kid.
The Matriarch will give you squeamishness because you have likely seen the movie The Birds at some point. Your kid will not have that experience yet.
The artwork is dark, bit is mainly of crows/ravens. You can explain that 'murder' is a grouping noun for some birds.
The main horror of the deck compared to others is the sheer quantity of villain cards that can appear each and every turn...and the Matriarch punishes for each and every bird that falls. You may want to avoid heroes with a majority of area effect attacks as the reciprocal damage will be immense unless precisely targeted and prepared for.
