"Let me handle this!" in asset form. I think it's pretty good for the right characters that are aiming to tank for their team.

Most guardians have good agility and will so they're moderately if not good at defending against the encounter deck. The only downside is that they have low sanity...but this provides some protection on that front.

2 health and 2 sanity soak for 2 resource is pretty reasonable. Accessory isn't particularly in high demand for guardians, the immediate comparison for me would be Holy Rosary. Both cost 2 and give 2 sanity soak, but this also gives 2 health soak, let's you take other players encounters and gives +1 to all skills instead of just will. On the flip side, it costs 1 more exp, you can't actively use the willpower outside of mythos, and you don't have a chance of getting bless tokens. Seems like a fair trade off.

You could probably use this in a variety of investigators but someone like Tommy, Zoey, Roland, Carolyn or Mark would probably be most interested in it. Zoey can get resources for engaging enemies, Roland can kill enemies for his passive, mark gets stuff for wounding his assets and Carolyn can heal herself up easily.

So this works like Taunt when another investigator draws a monster?

Seems very good in two player if that is the case.

Blah blah is this two hundred characters yet?............apparently not, but maybe it is now?

So for 4XP I can now have everlasting ammo thus totally breaking the balancing of firearms vs melee.

Good job FFG ;)

But seriously in those gimmicky sniper builds this is an auto include, the single biggest issue I had playing my Mark Harrigan sniper deck was running out of ammo. For 4 XP I can now never run out of ammo OR have to worry about shooting enemies off teammates.

Many of the excellent reviews compare J.K. to Dr. Milan Christopher, but it's also helpful to consider J.K. in comparison to a different card - the humble Laboratory Assistant.

Similarities:

• draw cards when played
• Seeker
• icon for skill tests
• Ally
• Miskatonic (so most investigators can have loads of ally slots, thanks to Miskatonic Archaeology Funding)
• even cost

Laboratory Assistant advantages

• costs less
• 2 sanity
• increases hand size by 2
• 0 xp (versus 2 with the new taboo for J.K.)
• Science

Jeremiah Kirby advantages

• 2 health
• +1
• draws more cards, probably
  • never, ever draws weaknesses
• Wayfarer

They're curiously similar cards in that they front load most of their benefit to the time they're played. That makes them particularly attractive with cards that trampoline them:

• Calling in Favors - bonus points if you can manage to use the point of soak before you bounce them. This makes a big investment in a high-xp ally more likely to work out.
• A Chance Encounter(0)
• Crypt Chill?
• I'm probably missing some...

Has anyone tried all these in a deck together? I'm considering it.

The team play feature is not just good for sharing the love of assets, but also allow others taking the play quota to skip Attack of Opportunity when playing those assets. Making this a great card for soak, Firearm, Spell users looking to refresh Asset even while in the mess of fighting. (The one who take play action to play Ever Vigilant (4) does have to deal with one AoO.)

If you are coming to rescue someone from enemies, you might not even have to engage it or risk friendly-fire. Instead just play this card. They might have just the asset that help dealing/evading that enemy on hand, only if they are Fast... well Ever Vigilant (4) is going to grant them that dream. It's like an uber-one-off-Fence comes flying to them : Works with all traits, no setup, and get both Fast and -1 discount! This allow team to recover from unlucky setup turns and make a come back even if enemies are already sticking in their threat area.

Since this card is looking to be the strongest at the start of scenario where you are all together, you may wish to communicate if you managed to mulligan into this card or not to influence mulligan decision of the other players in your party. (Or use Stick to the Plan)

Mulligan occurs in player order, the with this card as the lead may allow more efficient setup. Especially that it is "4 assets in total" as a group, you need to talk about how you share this quota. Below are relevant rules for reference.

Appendix III: Setting Up The Game

• ...
• Choose one of those investigators to be the lead investigator for this game.
• ...
• Draw opening hands. Each player draws 5 cards. Each player, in player order, may mulligan once at this time.
• ...

In Player Order

If the players are instructed to perform a sequence "in player order," the lead investigator performs his or her part of the sequence first, followed by the other players in clockwise order. The phrase "the next player" is used in this context to refer to the next player (clockwise) to act in player order.
