Royal Flush
The card itself is a good idea if you struggle seeing Jumbo index across a table. I have players that regularly need the community cards read out loud when the dealer is at the far end of the table.I know, I've peeped them but really can't imagine ever using them. I think I would consider using them if not for the little suit. If you're going huge, go all the way, don't give me a lil club next to the huge club.
That said, the execution on the Magnum card is terrible. Perhaps a Jumbo index for the peek and a full card width number or letter, with the suit in the background.
Then again, any new concept will always bump into resistance. Heck, there is always a comment made when my players move from one table to another because I use different setups on each table.
