Notes & Combos

Play 3x Grief, I forgot to play the 3rd one.

Broadbull-Drident is an option, but the deck currently has a bit of a harder time make r4nks than usual.

Probably should play Dingirsu and Ain since without doing consistent r4nks, the focus is a lot more on therions to board break and Ain helps a lot.

Cross Sheep is another card worth considering to help make r4nks much more consistently but it's fine.

Merrymaker is an F&V target yes.
