Hey there. So I know that ID cards aren't in Modern Age now, but I wanted to see what ID cards you'd utilize with FF figures.

Small list to start you off: Wolverine wanted and X-Men ID (several characters in set)
Red Hulk ID (1 additional in set)
Black Panther ID (2 figs, but not Black Leopard)
Hulk ID (2 Banners and Cho)
Nova ID (both versions of Raye)
Spider-Man ID (two versions in set)
Ms. Marvel ID (can call Kamala #50)
Sandman ID (Frightful 4 version)
SHIELD Level 7 [ridiculous amount of choices]:
Wolverine #11, Ghost Rider #26, Invisible Woman #34, Silk #51, Agent Venom #55, Hulk #56, Doom 2099 Revolutionary

Or would you just use them to attempt to sustain #54 Wolverine longer?
I Don't Stay Down Easy: When Wolverine would be KO'd except by this Trait, instead put him on this card with 4 Healing tokens. At the beginning of your turn, remove a Healing token. When you remove the last one, place him on the map on click #6 within 4 squares of a friendly character with the Fantastic Four keyword. If you can't, KO him. Protected: Pulse Wave.

So with the trait and the timing of ID characters leaving at beginning of turn. It should be the active player timing choice to take the last token off Wolverine then can remove the ID character that came into play the previous turn.
