Notes & Combos

Kristya lock is boring. Also this build is suboptimal, I'm running 2 Diviners because resolving the card feels good not because it's a good ratio.

Dogurad is there to theoretically go against Lunalight but honestly I just wanted to play with the new cards.

Vingolf felt really nice to push through hand traps.

Trias is just funny, not good. But **** the card is fun, Master Dispersion into three fairies to trigger Trias is so satisfying!
