Ok. I have gone into great detail and even just did privet 1v1s to test this with a friend. Cloud, PC on my turn while equipped is still going to the grave when i attack with celestial armor (So i should have indestructible) my brother blocks with a 2/3 flying creature with death touch and both cards go to grave. I made sure he no other effects. -/- counters, blight, infect, nothing like that i made sure for science. In Magic arena my cloud goes to grave every time. We tested against a 8/8 lion that gets +1/+1 counters when he gets life i let him get to 8/8 and i attacked with cloud on my turn and cloud went to grave. Its important to note this is simply a trade in combat damage. "Lethal damage won't cause cloud to go to grave" I've been playing magic a long time and have had issues with how indestructible works. After extensive googling and talking to some game store vets. This should not happen. TLDR Cloud equipped, should have indestructible on my turn. Brother blocks with enough to take out clouds toughness and cloud goes to grave. Even tho lethal combat damage to indestructible DOES NOTHING. PLEASE FIX
