Avengers Team Charter
Plot Twist
Threshold Cost: 4
As an additional cost to play Avengers Team Charter, discard an Avengers character card from your hand.

Search your deck for an Avengers character card and add it to your hand. Shuffle your deck.

Ongoing: Affiliated characters you control have the Avengers team affiliation. [This is in addition to their other affiliations.]

BE IT KNOWN, That we, the Avengers, have banded together to protect and safeguard the planet Earth...

hmmm I like it, its just I would think that the Avengers search card would be called AVENGERS... ASSEMBLE!!!

I thought of that too. But to me, Avengers Assemble would go something along the lines of what Teen Titans Go! does.

If I had to choose an effect for that:

Avengers ASSEMBLE!
Plot Twist
Threshold Cost: 2
Recover target Avengers character you control. If you control another non-stunned Avengers character, ready that character and it causes no breakthrough while attacking this turn.

i think you should have it cost 2 seeing as how you wouldnt be able to be used on turn 1 anyway and it won't fall victim to not so fast. ^_^
