I am carrying:
US Bank Flexperks Sig
AMEX HHonors
Chase Freedom
Citi TY Pref
Next card on my list:
US Bank Cash+
All the cards in my siggy are in my wallet. Usage details:
TD Bank Easy Rewards: 5x on groceries, gas, restaurants, and utilities until Feb 1st.
Orchard Bank Secured Card: Used once a month on a small purchase to keep it looking active
Chase Freedom: Use for it's 5x categories, but this quarter is a no-go for it 
so I use it for the 1% cash back on all my "other" purchases that don't utilize TD's categories
JCPenney Platinum Credit Card: ALWAYS use at JCPenney! Every $100 = $10 off coupon for next month, up to 10 coupons a month!
Shell Drive for Five: Use at Shell station once a month to keep it active
Also have my TD debit card, ATM card, and GACU ATM card, along with my Target Debit redCard for when I pop into Target and want that instant 5% off 
Then of course my license, student ID, miscellaneous reward cards, JCPenney discount card.
I'm proud to say that Capital One is no longer in my wallet now that I have a CSP.
Chase Sapphire Preferred -- everyday spending + bills
Walmart Store -- gas (15 cents off/gallon) or Sam's Club since they don't take Visa
Discover More -- just in case I happen to make a purchase that can get 5% back, or if I'm at Sam's Club since they don't take Visa, or ShopDiscover
Amex Blue Cash Everyday -- for those rare occasions I'm buying gas or groceries somewhere other than Walmart
Target REDCard -- maybe used once or twice a year, but better to hold it all the time than miss out on 5%
Chase Visa Debit -- used only for ATM deposits/withdrawals. I'm thinking about having them issue me an ATM-only card and just keeping this one at home in case of emergency.
Everything else is [RF]ID or loyalty cards, but most of those are in my phone. I would carry my Freedom card to use on smaller purchases, but it's the one card that's carrying a (0% promotional) balance; I was still using it for a while with Blueprint Full Pay (and thus avoiding interest while carrying the balance) but it got too complicated to keep track of. With the way Chase is always sending me 0% access checks, my Freedom basically acts like a Slate.
Right now all spending goes through CSP. I'm trying to get that bonus!
Chase Sapphire Preferred (dining/travel)
Chase Freedom (5% bonus, everyday spending for 10% + 10 bonus point)
Amex BCE (3% groceries, 2% gas when freedom doesn't cover either)
Ally Debit Card (Free atms everywhere!)
Capital One Platinum $750 (3/11) | Macy's $2K (1/12)
hmm ill update:
Citizen's Bank Credit Card-5% on gas and groceries until jan 1% on everything else (will be pc'd to other card for 3% on most used category and 1% on everything else)
Chase Freedom-5% categories
Amex Zync-Amex Charge Card
BOA and Citizens Debit Card.
every other card is sd unless i go somewhere specifically like best buy, walmart, kohls etc...
