I ran into an interesting situation and am still new to judging but when playing commander with some friends I played corpse dance, in response someone exiled my graveyard. since corpse dance doesn't target what happens to the card since I paid the buyback. does it return to my hand or end up in the grave. I tried looking this up but could not find this situation and ruling anywhere.

I believe, since it doesn't target anything, it resolves as normal and goes back into your hand.

Dominik is correct for exactly that reason. Corpse Dance resolves and does as much as possible, where “as much as possible” means going back to its owner's hand.

ok thanks for clearing that up for me I thought that was the case but told my friends I would check to be sure.

Right… I misinterpreted what you meant by “doesn't have a target”. Carry on!

Adam, Corpse dance checks to see which creature is the top creature in
your graveyard on resolution. Because it does not have the word target on
the card at all, it does not target. Therefore when it goes to resolve the
spell cannot be countered for having illegal targets because it didn't have
any targets to begin with.
