Sort of a follow-up to Can Hour of Devastation kill Heliod, Sun-Crowned?
Let's say my opponent has two Benalish Marshal and Heliod, Sun-Crowned. I cast Hour of Devastation. Per murgatroid99's answer, Heliod survives.
If my opponent next plays some flash creatures or enchantments that turn Heliod back into a creature, does it still have 5 damage marked on it (+ is no longer indestructible)?
