More land, most likely leaning White. You may have 22 two drops but you might run out of steam after that and then you have those six drops that will likely be
dead weight.
You're maybe light on fliers to the most from
Winged Words (turn 4 earliest you could cast it at a discount).
I might also look for Healer's Hawks to add: it evades which the Chaplain does not do. It flies making
Winged Words cost less earlier and benefiting from the Eagle. It's a 1 drop which you don't have.
Perhaps the Messengers can work for you but you really would want the other Yanling in play. This leads into your Planeswalkers being possibly being too expensive to come in an make a difference.

Capture Sphere and
Sleep Paralysis, see the
FLASH on the Sphere when everything else is the same means it could be used on your opponent's turn to hopefully shut a creature off.
