Shogun I think we need a bit more info... what are you looking for? where do you spend?
Cash back: Citi Double Cash - nice overall spend, Sallie Mae for 5% category spend
if you shop at Sam's Club: their MC which is pretty nice too
Travel cash back: Arrival+
Hotel card: Chase IHG
Sock drawer card with free money? ..oh no that is not fair but possible: BofA BBR
those are the ones that come to my mind...

While going through them, I noticed I only had one MC. It's a Barclay NFL card, not WEMC. I have several Visas, 2 AMEX, Discover and some store cards. So I was wondering.... what would be a good MC to throw in?
Awesome increase in your scores 
If you travel alot, using AA the Citi Aadvantage WEMC Is nice. Good sign up bonus which is worth more than 1cpm. Bare minimum the 50k miles would be worth $1k used right your value could be substantially more.
Again only if you travel.

For a very long time, the CSP was my go-to World MasterCard. It suited the purpose very nicely until Chase forcefully converted it to Visa. Since then, I've been using the Citi AA World Elite MasterCard (not the Executive), and it's been great.
