A1 Is my favorite. It looks well balanced and I like the thickness of both the letters and the underline. I really like how the spade forms the circular cutout in the line though I'm not 100% sure I would break the line. I'd have to see it to know for sure how it would look best.
Aaran Casey makes a good point about the red spade. I'd like to see a cleaned up version with red lettering for POKER and a black spade but I really do like the coloring better this way (however inaccurate to real playing cards it is). What if you changed the spade to a heart? That way, you can keep the coloring.

yeah I will consider the heart but I think my friend(the client) wouldn't like that. Thanks Jon.
