Looks cool.

Fake. Spelling errors everywhere. Also, 1 rare card in a set would be POINTLESS as it would be worth what the whole set is worth and the other cards would be 2c each.

OMG SHOW PROOF! ISAAC NEEDS SOMEEEEEEEE.

Source?

This looks fake but it will probably eventually happen anyways.

comming

Fake, I think Valve knows how their characters are called. "Jocky" LOL.

L4D clicky

BOI clicky

who the f*ck is Lewis??

I like those Binding of Isaac cards. I would like them. Wish they were legit. But a type of cards that I really want are Garry's mod

Fake as there are no spitters/chargers in l4d1.

Would like to get Binding of Isaac ones, hope it get's implemented into it soon D:

Oh god the misspellings.

Unless literacy levels at Valve Towers have plummeted, these look faker than a four dollar note.

FAKE.

Protip: All cards are rare, FOIL cards are the rarest, sets wont ever be more than 10 cards unless they drasticly change their drop limit policy.

Lolol. Just came out.
