Okay let's say that I have a Darksteel Colossus or a creature equipped with indestructibility or creatures with eldrazi monument in play. Do they survive a Day of Judgement and if not why? the rules say: If a permanent is indestructible, rules and effects can't destroy it. (See rule 701.6, "Destroy.") Such permanents are not destroyed by lethal damage, and they ignore the lethal-damage state-based action (see rule 704.5g). Rules or effects may cause an indestructible permanent to be sacrificed, put into a graveyard, or exiled.
