Cc query

Hey All So i have few cc like amex travel, axis atlas,hdfc bonvoy , one card and rbl I am on verge of closing RBL as its useless for me. One card i dont wanna close because of good limit. I heavily transfer points to marriott bonvoy and Maharaja Air India from others. Can you suggest one cc which will support that purpose . Sole purpose is transfer miles to airlines or hotels.
