It's a bit pricey at 4 XP, and it takes up an Arcane slot (precious to at least some Seekers), plus requiring 8 cards in hand. Is it worth it?
This card essentially makes one event Fast each turn. About a third of all events are already Fast, but the ones that aren't often trigger Investigate (or, occasionally Fight) actions, so this card could theoretically give Seekers 4 actions/turn fairly regularly and allow for some "no Attack of Opportunity" actions to get things done while under Enemy pressure. Play Burning the Midnight Oil to get 2 resources and maybe a clue, avoiding the Attack of Opportunity, then using the resources to pay for "I've got a plan!" (2) or Persuasion to get rid of an Enemy? As Ursula, getting a "Fast" Seeking Answers (2) to clear a location, then running a couple of locations away for a Special Ability Investigate?
Who likes it? Harvey has the hand size and Draw. He doesn't start with a ton of Events, but there's no reason you can't change that. Mandy has Draw, ways to increase hand size, and access to a lot of Events. Daisy probably doesn't, unless she's going with Spell Events over Assets, and poor Norman can't take it at all. Does Joe Diamond want it to make his entire Hunch Deck Fast?
