There are wider problems than just cards. Jorogumo are good, no doubt, but they're ML5 on their main attack immediately after your opponent draws a hand. It's sign posted considerably, any player worth their salt will see this coming. There are ways of neutering them (slow, paralyse, they're Df5 in a game with increasing amounts of HtW and HtK ignoring, they're activating early so Eat your fill isn't going to matter all that much, and so on). If your goal is to demostrate publically, then Torage are better for the additional VP. If you're after a symbol then great, but 9SS for that? There are better choices.
And so on.
Fun, sure, but not worth building a crew around imho. Remember this is, at it's cheapest, 25 Stones just to be able to do this with two spiders.
