Layers, humility and a weird board state.

[zeus-online]

Okay, so i was thinking of making a casual deck based around these 3 cards: Humility, Living plane, Night of soul's betrayal (or rather based on getting all 3 into play...)

But since layers is one of the few area's of the rules that i'm not all that comfortable with, what happens in this situation:

I've got: Humility, Living plane and night of souls betrayal in play....Does all lands and creatures die? or do they get -1/-1 and then become 1/1's?

Does replenishing them in make any difference as to the outcome? (i assume that if i can get the desired effect by playing them one at a time, there's a way to make it work by casting replenish)

Is there any particular order i need to cast them in?

Living Plane's type changing effect applies in Layer 4.
Humility's ability removing effect applies in Layer 5.
Humility's P/T setting and Living Plane's P/T setting abilities apply in Layer 6b; since they do the same thing the order they apply in is irrelevant to you.
Night of Soul's Betrayal's P/T effect applies in Layer 6c.

The order they come into play is irrelevant for your purposes.

So basicly:
They become 1/1's...humility makes them into 1/1's with no abilities and night of soul's betrayal wipes them out?

Yes.
