I assume it works with Dark Prophecy, right ? I'm not sure if using both the result is:
a) I can't select a special token with Dark prophecy as they are now considered as "0" tokens or
b) I MUST select one of these tokens by the effect of Dark prophecy and I treat it as a "0"
but either way now I have very low chances to have a big negative modifier.

For TCU in expert difficulty, of the 15 tokens, 5 are now considered as "0" tokens and the worst case is, depending on the interaction between both cards (see above):
a) because I can't select the special tokens, I can choose the one I want among the 5 and so between -2, -3, -4, -6 and -8 I choose the -2
b) if there is a special token among the 5 I must select it and so I resolve a "0" or there isn't a single one and I'm back to the case above

So by combining both cards in expert difficulty I spend an action to be sure that the following action I won't have worse than a -2 modifier for my attack with Shotgun, Sawed-Off Shotgun, Beretta M1918, or other, right ?

Firstly, this is not intended to be an in depth review of the card. I think the other current review of this card does a pretty good job covering when this card is good and when it isn't.

No, my aim is more specific: i think this card shines when used to counter any enemy weakness. Some investigators have nasty enemy weaknesses that can pack a punch or are extremely resilient:

• Watcher from Another Dimension Specially given how Patrice can cycle her deck several times per game.
• Tommy Malloy is a pain to fight but if you run a survivor with Nacho, they can basically delete him from the game.
• Hoods (the card that motivated this post)
• Stubborn Detective Silver Twilight Acolyte (beware the doom though) Your Worst Nightmare (as somebody mentioned) ... sadly doesn't work in the Accursed Follower which makes me very angry.

These are mere examples though. The silver lining is that you can cycle your deck while these remain in play completely harmless. You can (for instance) fend off a Guardian of the Crystallizer from your Trish player and let them carry it around for nefarious purposes. If your Mandy keeps reviving their enemy weaknesses you can pin them on the board so they can do their seeker things even better.

All in all, i think it's a great card to make your deck safer and you shouldn't underestimate it.

Is this card available via deck creation or upgrade? What means base value? Will Maginyfying glasses and Dr. Milan Chritophers +1 book still be added or are they worthless with Monstrous Transformation? I think this would be super cool with Amanda.

One of my favorite Signature cards in the game.

This card is basically A better version of the .45 Automatic, In fact I would say you shouldn't even get the 45. Automatic. Lets Discuss

What this card does better: Cost 2 resources less Gets an additional fist And the reason this is one of the best signature cards, It essentially has infinite ammo.

The only 2 down sides of this card is the ammo capacity and that it uses 2 hand slots, But even the ladder can be solved with Bandolier which goes well with Tommy's ability. Even if you have a better weapon in your hand slot this card also has pretty good resources.

Back to the ammo discussion, You can draw this card at this start of the game and use it all game reliably without worrying about ammo. So, in summary I think this card is one of the best weapons in the game.

This one looks like a decent target for True Magick, since it is not something you want to put down for real ended up having nothing to do until the situation comes. By keeping it in hand you can now also commit like Guts.
