I destroyed my opponent's permanent with Putrefy, an Instant that reads:
Destroy target artifact or creature. It can't be regenerated.
He returned it to the top of his library with Golgari Thug because it went to the graveyard (is it supposed to go to the graveyard?). Golgari Thug reads:
When Golgari Thug dies, put target creature card from your graveyard on top of your library.
So whats going on? I destroyed a card and I thought it cannot be regenerated. When Putrefy says, "It can't be regenerated" is it actually a counter for a card that can be regenerated? For example: Opponent has Manor Skeleton that has: “{1}{B}: Regenerate Manor Skeleton”. I target it with Putrefy. Is his Manor Skeleton's regenerate ability countered and does it go to the graveyard?
Does, "It can't be regenerated" mean "It can not be regenerated from the graveyard", or does it counter a regeneration ability?
