Best playlist to get a Castle DLC map?

I’m trying to get the Castle dlc achievements, but the Castle maps very rarely appear. Any suggestions on how to earn those achievements? Thanks in advance,
JWILD

p.s. If you have the castle (and Crimson) dlc and want/need the achievements feel free to message and/or friend request me.

The only playlist that contains all three Castle maps is CTF. But as it stands right now you’ll never get a DLC map.
