Turn over (rites/aeons)

Definitely not all that tuned, but it's my favorite janky 'play only once or twice a month because once it goes off it stops being fun for a while' combo deck. The ideal goal is to accelerate with into the north, rites of flourishing, lotus blooms, and prismatic lenses to get to the point where you've established a board position which will allow you to have 2x rites, crucible, and then walk the aeons each turn. Teferi shuts off responses once you've got the combo ready, so you can cast him EOT before you go off to either bait out a counter, or keep them from countering on your next main phase. 2x primal commands and gaea's blessings help keep you from decking yourself, and harmonizes, visions, and drifters help draw into the combo. Chronozoas just love infinite turns as well.
