i'm not familiar with soul sisters. how does that work?
Done. I really like that, thanks for the suggestion!
Sure, it's just a dupe for torpor orb. Cast Eater of Days or Hunted Horror. It resolves, and then its ability goes on the stack. Then, you activate sundial, its ability goes on top of the stack exiling everything underneath it (such as the centaurs and the skipped turns). You can also use it to cancel out instants and activated abilities that your opponent casta on your turn.
Done, thanks!
