So I understand that if you cast an -x/-x spell, an indestructible creature will be placed in the graveyard if the creature's toughness is x. Also, I understand that the indestructible creature will not die resulting from combat damage.
My question is, do indestructible creatures have their toughness reduced due to combat damage, it's just they dont die from the reduction or that they do not even have their toughness reduced from combat damage?
Technically (if I'm understanding your question correctly) damage does not reduce toughness of a creature.
For example, if you lightning strike a 6/6, it deals 3 damage to it. It's toughness is still 6/6. Damage remains on a creature until end of turn OR until its enough to kill that creature. The toughness; however, does not change (due to that damage).

Damage does not reduce toughness at all (unless the source has Wither or Infect). It just stays "marked" on the creature until end of turn.
A regular 5/5 creature that is dealt 5 damage is still a 5/5, not 5/0. Death by lethal damage (marked damage equal or greater than its toughness) is destruction. So if the 5/5 with 5 marked damage is indestructible, it won't be destroyed by the lethal damage.
-X/-X effects actually do reduce toughness, and death by 0 toughness is not destruction so even an indestructible creatures go to the graveyard if their toughness reach 0.
I'm curious if he's asking about the combination. If, for example, you Lightning Strike a Soul of New Phyrexia that has activated its ability and then Ulcerate it, does it die? The answer, which you can probably piece together from the other answers, is no. It will be a 3/3 with 3 damage marked on it until end of turn, but won't die because it still has Indestructible. The effects would "stack", in a way, to kill a 6/6 that didn't have Indestructible, though.

Right, Soul of New Phyrexia will be a 3/3 with 3 damage marked on it. If it has indestructible, it won't be destroyed. If it does not have indestructible, then the game will see a 3/3 with lethal damage and it will be destroyed.
I think I get it now, basically an indestructible creatures is only marked by things that cause damage, nothing actually effects its' toughness. So the -x/-x effects would still have to be for the full toughness of the indestructible creature for it to go to leave play.

From these responses, why would Soul of New Phyrexia become a 6/3 from Lightning Strike? From all the responses, it seems that since the soul is indestructible, the damage only gets marked on the creature instead of actually reducing its toughness? So from what I am saying it would take two Ulcerates to kill the soul. Is this correct?
If people are sick of reading about stuff just stop taking part. You have 100% control over what you read. Simic Ascendancy isn't going to get banned just because you didn't tell someone to shut up on the internet.

You're still mixing things up.
1) Damage.
Regular damage only stays marked on a creature. Any creature. Marked damage is cleaned at the end of the turn.
The damage doesn't ever change the creature's toughness; but the game is constantly comparing the two values - the amount of marked damage and the toughness. If they are equal or the damage is greater, then this is considered lethal damage and the creature is to be destroyed.
"Indestructible" literally means "can't be destroyed"; a creature with this ability is dealt damage and keeps marked damage the exact same way any other creature does, except it doesn't die from it.
A 6/6 creature dealt 3 damage is still 6/6. This is not special for indestructible, that's just how damage works in any creature.
2) -X/-X effects.
Effects that reduce toughness work as normal. If a 6/6 creature gets -3/-3, it will be a 3/3. If the 6/6 was indestructible, it is still a 3/3 indestructible creature.
If the now 3/3 it already had 3 damage marked on it from before, or if then receives 3 damage (same thing, really), then this damage is now lethal and it would be destroyed. Being Indestructible still works as before, so it just isn't destroyed.
But if it gets another -3/-3 effect, it reaches 0/0. Having a 0 toughness means the creature goes directly to the graveyard. This is not considered destruction, so that's one way to kill an Indestructible creature.
My question is, do indestructible creatures have their toughness reduced due to combat damage, it's just they dont die from the reduction or that they do not even have their toughness reduced from combat damage?
