Notes & Combos

just remember that sigma locks you!

Getting 3 names in GY is hard sometimes, funnily enough the format is low power enough that having stuff sitting on board, waiting to get popped so your mathmech names go to gy is doable, sometimes.

you can dump nabla over sigma with circular if you open the time thief combos first
