I attack with a Vector Asp and use his activated ability to give him infect until the end of the turn. It's blocked by a 2/2 creature and goes to the graveyard.
If I cast Corpse Cur next, can I return Vector Asp to my hand from the graveyard?
On the one hand, the Vector Asp did have infect until the end of the turn. On the other, he may have lost that by going to the graveyard. Which is it?
