If I have {avacyn angel of hope} in play and use {hour of reckoning} to clear the way for my attack do my creatures stay due to there indestructibilty ?
Yup. Destroy effects have no effect on indestructible creatures
Nice I thought so that makes me very happy especially when I use {palisade giant} and {avacyn angel of hope} together
Just watch out for things like {Terminus}, {Cyclonic Rift}, {Mutilate} and possibly a few others.
