base: masonry / wheel
It can't be Masonry, since even if you want to go for Wheel+Masonry Monument combo, you can just as well draw the Masonry on turn 2-3. In your starting hand, you want something else that can be useful.
I think it's gotta be Wheel + Domestication or City States.
Domestication is nice because you can draw while melding, so you're always taking double actions, but it's vulnerable to City States until you get at least another crown.
City States keeps your Wheel basically unshareable and can make it a bit harder for them to use Sailing without a share, which puts you in a pretty dominant position with the downside being that you actually have to use meld actions, unless you find Domestication.
