• Captain America's Shield: +1 DEF and retaliate 1.

I know ZaneBrick posted the text from Captain America's Shield below.
But I prefer having the actual link for easy access ;)

There is an error here. Card 104B in the Age of Apocalypse should be The Towering Citadel side scheme. Instead of No Longer Worthy Attachment. I hope it can be fixed. 200 character 200 character 200 character 200 character 200 character 200 character

*Cracks fingers* - "Alright, time for some maximum effort"

- Deadpool impersonating Wolverine

you take 2 damage, defeat a minon. You take 2 damage, defeat another minion. You take 2 damage again, defeat another minion; you finally take another 2 damage and hit the boss because he is looking bad at you.

Then you fip back to alter ego, shuffle the trick back to your deck (optional), Draw 3 cards now or in the next turn, and recover for 6 because you are Logan (8 instead if you learn how to properly spend your Down Time)

Bonus points if someone made you grab it at the proper time via Generation X, of if you made it by yourself via Keep Up the Pressure (that way each instance increases its damage by 1)

If I understand the card correctly, the condition for the interruption is taking any amount of damage, so the source of the damage could be yourself. Then this card cant interact with cards like

• (Wolverine (Hero) - Wolverine's Claws)

• (Wolverine (Hero) - Berserker Barrage

• (X-23 (Hero) - X-23's Claws

• (Deadpool (Hero) - "Yoo-Hoo!"

• (Deadpool (Hero) - Maximum Effort

• Basic Ally - Grant Ward

And lot of Take 1 damage cards and effects that I wont list here because preventing 1 damage with this card is questionable

I spent an hour looking for good targets for this card. Then my browser crashed, so here is a summary :p

I love cards that encourage multiplayer and cooperation! BUT....

Why it’s good (?):

• Cyclops dreams about it at night :p
• It’s a WILD resource. Really not that useful because there are other cards more useful like POWER OF LEADERSHIP or DIVERSITY…
• It might allow a rich player to use their resources for the group (unless they could already do it because most encounter cards are Actions…).
• It allows other players to help with Obligations. But doesn't avoid you going into alter-ego (like most of them ask), and they can easily be discarded anyway.

Why it’s bad (!):

• Useless in solo (obviously). And only becomes playable at 3+ players to maximize the numbers of players that can benefit from it.
• It doesn't cost 0 but 1 card from your hand, i.e. 1ER (Effective Resource).
• You need to play it BEFORE someone else pays the cost, only during YOUR turn.
• If you play COORDINATED for 1 ER rather than paying 2+ ER to get rid of the encounter card because you think it can wait until someone can spare the resources, well… maybe it’s NOT such a bad encounter card… otherwise you just get rid of it immediately!
• On a 1 cost encounter card…well why don’t you just pay the actual cost instead?
• On a 2 cost encounter card…can’t you spare just 1 more resource? Maybe your teammate can because…
• Most encounters cards or abilities can be triggered by everyone anyway.
• On a 3 cost encounter card…it might become decent, but you still pay an extra 1 ER as a group. And again, actions can be done out of turn.
• On an encounter card requiring an unlimited amount of resources, it may become a tech card you add in your deck. But I don’t see a good use case (see below).

The different types of encounters cards:

• This is the part I lost during the crash of MCDB, but basically, no card is worth attachng CE to. It either doesn't make any difference who actually triggers it (like Black Widow, etc.), is already "cheap" to discard (like Zola's Algorithm), or you can just leave it in play because it's not too bad.
• Big cards like We Are One and Advanced Glider are okay targets, but maybe you should just add a generator and attack events in your deck instead if you're looking for a tech card.
• Finally City Streets (for a teammates with multiple bug ATK allies) or mod set like the one with Dragnet and its variants could be the best target, but those are not great targets...

To sum up:
It's a trash card! And saying this hurts me because I want to encourage multiplayer shenanigans :/
Coordinated Effort will only ever be useful in the very edge case of you having it in hand AND having somewhere interesting to play it on AND being 1-2 ER short to pay the actual cost AND the situation can't wait next turn AND someone can pay the cost AND you play before them! Pretty rare use case… You just don’t add a card to your deck in the hope this will happen.
