Playing Miss Doyle with Charlie Kane in a Charlie Kane deck inspired by the mediocre film, Evan Almighty (https://www.imdb.com/title/tt0413099/) - This Charlie likes his animals, has a Rod of Animalism and Miss Doyle is perfect for him - two allies in play for the price of one ally slot three (or two with the Rod) resources and only one action... plenty of icons!
Miss doyle gives one wild icon, so +2 to any test, and with Hope, Zeal or Augur there is the double benefit that covers all skill tests other than will tests:
Hope gives you an evade at a base skill of 5... or gives you +2 to either intellect or strength Zeal gives you an attack at a base skill of 5... or gives you +2 to either intellect or agility Augur gives you an investigate at a base skill of 5 or gives you +2 to either strength or agility
So just with Miss Doyle and your free cat lieutenant in play, say Augur, you get to investigate at 7; strength test at 5, agility test at 5 or will test at 4 once per round.
All in, if you are playing a simple Charlie Kane deck for the icon boosts then once powered up Charlie usually gets one good skill test per turn, but with miss doyle in play as well as a few others, its probably two good skill tests, and that is before any shenanegans with automatic successes on offer. With the Rod of Animalism, those three fast cards (Hope, Zeal and Augur) become zero-cost as well (so long as you haven't played another creature that turn.) It's really helpful not to have the resource burden if you want to change cat lieutenant to take advantage of that auto success.
One slight Scarlet keys related semi-spoiler-related question...
If one of the cat-lieutenants (Hope, Zeal or Augur) end up as a "hollow", and Miss Doyle is later discarded, do they get removed from the hollows.
As i read it, being set aside as a hollow is an out of play area... but if Miss Doyle leaves play through normal means (is discarded probably through taking damage/horror) then you search for hope, zeal or augur from the hollows and set them aside out of play... ready to be brought back if Miss Doyle re-enters play?
