The most boring, unimaginative and weirdest upgrade in THE WHOLE game. For 2xp you get "Fast"? What? Such a bad upgrade to one of the most classic cards in the entire game, the one that was designed ages ago and started making a whole archetype with Dark Horse. I know some folks like to say "heeey but you can save it in your hand if you play somebody like Minh and then when an enemy shows up you put it into play hoho i am so smart" yeah, but you can do that with the other Seeker cards like "I've got a plan!" or Occult Invocation, you know, the card that is meant to be saved in your hand for when you need it, which is why it is an EVENT card? And with it you just spend a bit of resources and blast 2-4 dmg and be done with that enemy that is sooo problematic as you say, and still keep 2xp and save yourself a hand slot.
They could have given us another +1 to combat maybe, or make it do something else, maybe another ability that is a reaction which says if your last resource is spent by the above ability, gain 1 resource. That way it would make it so when you destroy the only enemy with it you still get 1 resource for other cards when you need it and would make an interesting combo card. Such a disappointment :(
