So I was just wondering Say I have humility out and someone activates a planeswalker's ability to turn into a creature, would he turn back into a planeswalker at the end of turn or stay a 1/1 creature with no abilities?
If someone activates Sarkhan's ability to turn into a creature the creature will still have indestructible, flying, and haste and still be a 4/4 since the timestamp on the ability granting the abilities and setting the power and toughness is later than that of Humility's.
It will then turn back into a planeswalker at the end of the turn because that is a part of the ability. It doesn't matter that the ability is gone (technically it loses that ability when it turns into a creature to begin with). It will still turn back into a planeswalker at the end of the turn.
WizardMN, this confuses me because I thought that if I had Humility out out and activated and Inkmoth Nexus it would end up a vanilla 1/1. Am I missing something or misremembering?
I thought that it doesn't matter when or how the creature got there it still becomes a 1/1. So does this mean morph cards have a way to morph as well? I guess I don't understand but hey if you're right you're right, thank you.

Determining whether a continuous effect uses dependencies or timestamps occurs "within a layer or sublayer", that is, for each layer or sublayer individually (C.R. 613.6, 613.7). In layer 4 (C.R. 613.1d), Inkmoth Nexus is determined to be a creature, so that Inkmoth Nexus will be affected by Humility. In layer 6 (C.R. 613.1f), timestamps will be used, since neither effect on abilities depends on the other (here the effects are "...lose all abilities" and "with flying") (C.R. 613.7a, 613.7, 613.6), so that Inkmoth Nexus loses all its former abilities and gains flying.

Not the ones that are creatures when face up. The way morph works is kinda weird in that the face down permanent has no actual abilities, but you can take the special action of turning it face up for its morph cost, if it would have a morph cost if it were face up. Morph being an ability (even if it's not an activated ability, and it's not an ability the permanent has while face down), because of Humility, a creature card wouldn't have a morph cost if it were face up. A noncreature card like Zoetic Cavern would, since Humility wouldn't affect it, so it can be turned face up.
702.36e. Any time you have priority, you may turn a face-down permanent you control with a morph ability face up. This is a special action; it doesn't use the stack (see rule 115). To do this, show all players what the permanent's morph cost would be if it were face up, pay that cost, then turn the permanent face up. (If the permanent wouldn't have a morph cost if it were face up, it can't be turned face up this way.) The morph effect on it ends, and it regains its normal characteristics. Any abilities relating to the permanent entering the battlefield don't trigger when it's turned face up and don't have any effect, because the permanent has already entered the battlefield.
I'm a former judge (lapsed), who keeps up to date on rules and policy. Keep in mind that judges' answers aren't necessarily more valid than those of people who aren't judges; what matters is we can quote the rules to back up our answers. When in doubt, ask for such quotes.
