What should I do with my Venture X?

Long story short, I live in Alaska so my home airport is dominated by Alaska airlines. This also means I get the club 49 benefit which gives me 2 free checked bags flying out of it. I also get atmos points from paying my internet/phone bill every month. Currently my only 3 credit cards are Quicksilver1/Savor/VX, obviously really strong point multipliers. I just got the SUB on the VX card so now I’m in a little dilemma where I really should get one of the atmos CC’s, but I don’t know what I should do w/ my travel card setup or which atmos CC to get. Any suggestions on the best way to maximize my points?
