Having played with this card a few times personally, and with my party, I think all the talk of taboo and brokenness is pretty overblown (at least outside of solo). It does absolutely smash certain scenarios, like Doom of the Eztli mentioned below, but I generally think this card is in line or slightly above the power level for a 5 exp card in a heavily contested slot. It's expensive in both regards as well as resources, so it has to be worth running, and in that regard it is a very cool card. In terms of the stat boosts, they're of course great, but nothing you couldn't get in other places with other cards (and only Monterey and Ursula really care about the agility boost). The movement is cool, but it costs actions, and Seeker actions arguably the most valuable in the game (notice a lot of the taboo'd seeker cards have fast effects). In my personal experiences, other than in the aforementioned DotE, I hardly ever used the movement option (though maybe Daisy would more often since she gets it for free). The most powerful aspect of this card is probably the part that ignores attacks of opportunity. This is a godsend for solo seekers who have no ally to take out foes for them, but in multiplayer I don't think this actually changes that much for a seeker, other than being able to potentially drag enemies to their fighters (and even then they'd have to end their turns there). In my personal experience in 4 player games, the seeker has dodged one, maybe two attacks of opportunity per game on average, which isn't trivial but isn't enough of an impact to where I'd call it broken. You could say it's the sum of all these effects that makes it deserve a taboo, but personally I think 5 exp, 4 resources and a hand slot really demands a lot from a card (see cards such as Lightning Gun) and that Prophesiae deserves to be cool and high impact. It does really well in a few scenarios, but I think that's ok, with the sheer variety of scenarios in this game some cards are bound to break some. I've never seen it break a campaign anywhere near as hard as any of the taboo'd seeker cards, or even some of its contemporary seeker cards like Eon Chart. This was revealed the same day as Jeremiah Kirby and I think he's ended up the better card with a really cool deckbuilding puzzle. At the end of the day, 4 resources, a hand slot and 5 exp are a lot for one card (10 for two copies) so it should be powerful. But I don't think it's anywhere near the power level of what we've seen before for seekers. In defense of Prophesiae Profana, I rest my case.
