6/15/2010: Lethal damage and effects that say "destroy" won't cause an indestructible creature to be put into the graveyard. However, an indestructible creature can be put into the graveyard for a number of reasons. The most likely reasons are if it's sacrificed, if it's legendary and another legendary creature with the same name is on the battlefield, or if its toughness is 0 or less.
6/15/2010: Deathless Angel's ability doesn't grant an ability to the targeted creature. Rather, it affects the game rules and states something that's now true about that creature. The creature will remain indestructible for the rest of the turn even if it loses all abilities.
